A Comprehensive Guide to Choosing Between LDO (Low Dropout Linear Regulators) and DC-DC (Switching Regulators)

　　Selecting the appropriate voltage regulator is critical for the stability and efficiency of various circuit systems. Among the numerous types available, LDO (Low Dropout Linear Regulators) and DC-DC (Switching Regulators) are two common voltage stabilizers. This article will thoroughly explore the selection methods for LDO and DC-DC regulators, covering concepts, operating principles, characteristics, and application scenarios.　　A Comprehensive Guide to Selecting LDO (Low Dropout Linear Regulators) and DC-DC (Switching Regulators)　　1. LDO (Low Dropout Linear Regulator)　　1.1 Concept　　LDO stands for Low Dropout Regulator, typically used to regulate high input voltages to lower output voltages. It achieves stable output voltage by adjusting the conduction resistance of its internal transistor.　　1.2 Working Principle　　When the input voltage exceeds the output voltage, the internal transistor enters an amplified state. It dissipates excess power to regulate the output voltage, maintaining it at the set value.　　1.3 Characteristics　　Simple design, low noise, relatively low cost, suitable for applications requiring high precision. However, it has low efficiency and significant thermal distortion.　　2. DC-DC (Switching Regulator)　　2.1 Concept　　DC-DC refers to a switching regulator (DC-to-DC Converter) that converts input voltage to the desired output voltage by switching the state of a switching element (e.g., MOSFET).　　2.2 Working Principle　　DC-DC operates by periodically turning the switching element on and off to control the output voltage magnitude, while a filter removes high-frequency noise from the output waveform.　　2.3 Features　　High efficiency, capable of delivering substantial output power, suitable for applications requiring large voltage drops or enhanced efficiency, but involves complex design and relatively higher cost.　　3. How to Select?　　3.1 Output Voltage Range　　For lower output voltages, an LDO is more suitable; whereas for large voltage drops or higher output power requirements, a DC-DC converter is more appropriate.　　3.2 Efficiency Requirements　　When prioritizing power efficiency, especially under large voltage drops, DC-DC converters typically outperform LDOs.　　3.3 System Complexity　　LDOs may be preferable for simplified design and cost reduction; DC-DC converters are necessary when higher output power and efficiency are required.　　3.4 Ripple and Noise　　In applications sensitive to output ripple and noise, LDOs are generally more suitable than DC-DC converters because they produce lower ripple and noise.　　4. Application Scenarios　　4.1 LDO Application Scenarios　　Applications requiring high output voltage accuracy, low output current, and strict ripple/noise specifications.　　4.2 DC-DC Applications　　Applications requiring large voltage drops, high output power, and high efficiency, such as mobile devices, power amplifiers, and communication equipment.　　4.3 Comprehensive Considerations　　In practical applications, the optimal regulator type must be selected by comprehensively evaluating system power consumption, output load conditions, stability requirements, and cost factors.　　As common voltage regulators, LDOs and DC-DC converters play vital roles in electronic product design. Selecting the appropriate regulator type depends on specific application requirements, including output voltage range, efficiency demands, system complexity, and ripple noise. During the selection process, a comprehensive evaluation of all factors is necessary to ensure the circuit system operates stably, reliably, and efficiently.

ROHM launches SiC MOSFETs in TOLL package that achieves both miniaturization and high-power capability

　　ROHM has begun mass production of the SCT40xxDLL series of SiC MOSFETs in TOLL (TO-Leadless) packages. Compared to conventional packages (TO-263-7L) with equivalent voltage ratings and on-resistance, these new packages offer approximately 39% improved thermal performance. This enables high-power handling despite their compact size and low profile. It is ideal for industrial equipment such as server power supplies and ESS (Energy Storage Systems) where the power density is increasing, and low-profile components are required to enable miniaturized product design.　　In applications like AI servers and compact PV inverters, the trend toward higher power ratings is occurring simultaneously with the contradictory demand for miniaturization, requiring power MOSFETs to achieve higher power density. Particularly in totem pole PFC circuits for slim power supplies, often called “the pizza box type,” stringent requirements demand thicknesses of 4mm or less for discrete semiconductors.　　ROHM's new product addresses these needs by reducing component footprint by approximately 26% and achieving a low profile of 2.3mm thickness – roughly half that of conventional packaged products. Furthermore, while most standard TOLL package products are limited by a drain-source rated voltage of 650V, ROHM's new products support up to 750V. This allows for lower gate resistance and increased safety margin for surge voltages, contributing to reduced switching losses.　　The lineup consists of six models with on-resistance ranging from 13mΩ to 65mΩ, with mass production started in September 2025 (sample price: $37.0/unit, tax excluded). 　　Product Lineup　　Application Examples　　・Industrial equipment: Power supplies for AI servers and data centers, PV inverters, ESS (energy storage systems)　　・Consumer equipment: General power supplies　　EcoSiC™ Brand　　EcoSiC™ is a brand of devices that utilize silicon carbide (SiC), which is attracting attention in the power device field for performance that surpasses silicon (Si). ROHM independently develops technologies essential for the evolution of SiC, from wafer fabrication and production processes to packaging, and quality control methods. At the same time, we have established an integrated production system throughout the manufacturing process, solidifying our position as a leading SiC supplier.• EcoSiC™ is a trademark or registered trademark of ROHM Co., Ltd.　　Terminology　　Totem Pole PFC Circuit　　A highly efficient power factor correction circuit configuration that reduces diode losses by using MOSFETs as rectifier elements. The adoption of SiC MOSFETs enables high voltage withstand capability, high efficiency, and high-temperature operation for the power supply.

　　ROHM has developed the 100V power MOSFET - RS7P200BM - achieving industry-leading SOA in a 5060-size (5.0mm × 6.0mm) package. This product is ideal for hot-swap circuits in AI servers using 48V power supplies as well as for industrial power supplies requiring battery protection.　　The rapid evolution and widespread adoption of AI technologies have increased the demand for stable operation and improved power efficiency in servers equipped with generative AI and high-performance GPUs. Particularly in hot-swap circuits, power MOSFETs with wide SOA are essential to handle inrush current and overload conditions, ensuring stable operation. Furthermore, within data centers and AI servers, the transition towards 48V power supplies, which offer superior power conversion efficiency, is progressing against a backdrop of energy conservation. This necessitates the development of high-voltage, high-efficiency power supply circuits capable of meeting these demands.　　Therefore, ROHM has expanded its line-up of 100V power MOSFETs ideal for hot-swap circuits in AI servers to meet market demand. The new RS7P200BM adopts a compact DFN5060-8S (5060 size) package, enabling even higher density mounting compared to the AI server power MOSFET ‘RY7P250BM’ in the DFN8080-8S (8.0mm × 8.0mm size) package, which ROHM has released in May 2025.　　The new product achieves a low on-resistance (RDS(on)) of 4.0mΩ (conditions: VGS=10V, ID=50A, Ta=25°C) while maintaining wide SOA of 7.5A at a pulse width of 10ms and 25A at 1ms under operating conditions of VDS=48V. This balance of low on-resistance and wide SOA, typically a trade-off relationship, helps suppress heat generation during operation, thereby improving server power supply efficiency, reducing cooling load, and lowering electricity costs.　　Mass production of the new product began in September 2025 (sample price: $5.5/unit, excluding tax).　　ROHM will continue to expand its product lineup for 48V power supplies, which are increasingly adopted in applications such as AI servers. By providing highly efficient and reliable solutions, we will contribute to reducing power loss and cooling loads in data centers, as well as enhancing the high reliability and energy efficiency of server systems.　　Application Examples　　•48V system AI servers and data center power hot-swap circuits　　•48V system industrial power supplies (forklifts, power tools, robots, fan motors, etc.)　　•Battery-powered industrial equipment such as AGVs (Automated Guided Vehicles)　　•UPS, emergency power systems (battery backup units)　　EcoMOS™ Brand　　EcoMOS™ is ROHM's brand of silicon power MOSFETs designed for energy-efficient applications in the power device sector. Widely utilized in applications such as home appliances, industrial equipment, and automotive systems, EcoMOS™ provides a diverse lineup that enables product selection based on key parameters such as noise performance and switching characteristics to meet specific requirements.　　・EcoMOS™ is a trademark or registered trademark of ROHM Co., Ltd.　　Terminology　　SOA(Safe Operating Area)　　The voltage and current range within which a device can operate safely without damage. Operation beyond this safe operating area may cause thermal runaway or damage; therefore, consideration of the SOA is essential, particularly in applications where inrush current or overcurrent may occur.　　Hot-swap circuit　　The complete circuitry supports the hot-swap function, which enables the removal or insertion of components while the device's power supply remains active. Comprising MOSFETs, protective elements, and connectors, it suppresses inrush currents occurring during component insertion and provides overcurrent protection, thereby ensuring the safe operation of the system and connected components.　　Inrush Current　　The high current exceeds the rated current value that flows momentarily when switching on electronic equipment. Controlling this prevents damage to devices and stabilizes the system by reducing the load on components within the power supply circuit.　　On-resistance(RDS(on))　　The resistance value between the drain and source terminals when the MOSFET is in operation (on). The lower the value, the less power loss occurs during operation.

Panasonic Industry Commercializes Conductive Polymer Tantalum Solid Capacitors (POSCAP) with The Industry's Lowest Profile*1 to Support High-Output Power Delivery Required for USB Type-C Connections

　　Panasonic Industry Co., Ltd., a Panasonic Group company, announced that it will begin commercial production of its two models of Conductive Polymer Tantalum Solid Capacitors (POSCAP), 50TQT33M and 63TQT22M. These capacitors are incorporated into power circuits used for information and communication equipment, including laptops and tablets. They offer an ultra-high withstand voltage and high capacitance in a body with the industry’s lowest profile of 3 mm, supporting high-output power delivery through USB Type-C connectors. Mass production for these models is planned to start in December 2025.　　These capacitors are ideal for voltage stabilization and noise reduction in power supplies compliant with USB Power Delivery (USB-PD)[1] 3.1. While previous USB-C connectors supplied up to 100 W (20 V/5 A), USB-PD 3.1 expands this to 240 W (48 V/5 A). This enables widespread use of USB-C connectors for high-speed data transfer and rapid charging, and is expected to further expand applications to larger equipment requiring high power output, such as displays.　　On the other hand, information and communication equipment such as laptops are increasingly required to be thinner and more compact. Capacitors therefore must combine an ultra-high withstand voltage, high capacitance, and a low profile in order to fit into limited space. Panasonic Industry began mass production of Conductive Polymer Tantalum Solid Capacitors (POSCAP) in 1997 and, as an industry leader, has continuously delivered first-of-their-kind products. Leveraging proprietary powder molding technology and film formation technologies, the company has newly developed two models that achieve both an ultra-high withstand voltage and high capacitance in a package with the industry's lowest profile of 3 mm.　　Through these unique device technologies, Panasonic Industry will continue to contribute to enhancing the functionality of electronic equipment, including laptops, while also reducing the environmental impact through smaller, lighter devices and lower material usage.　　Key features:　　1. Achieves both an ultra-high withstand voltage and high capacitance*2 to support high-output USB Type-C power delivery, in a 3 mm profile—the lowest in the industry*1—enabled by proprietary powder molding and film formation technologies　　2.

Contributes to reduced material usage lower environmental impact through low-profile design　　*1 As of September 18, 2025, Conductive polymer tantalum solid capacitors with rated voltages of 50 V and 63 V and capacitance of 22 μF or higher (Panasonic Industry data)　　*2 USB-Power Delivery 3.1 (180 W/240 W output) compliant high-capacitance conductive polymer tantalum solid capacitors with rated voltages of 50 V and 63 V, and a capacitance of 22 μF or higherDetailed features:　　1. Achieves both an ultra-high withstand voltage and high capacitance to support high-output USB Type-C power delivery, in a 3 mm profile—the lowest in the industry—enabled by proprietary powder molding and film formation technologies　　To achieve capacitor performance required for USB-PD 3.1 power supplies in a low-profile body, both high capacitance and a high withstand voltage must be ensured, despite their trade-off relationship. High-capacitance tantalum powder is necessary for electrode materials, but its fine particle size makes molding difficult, creating challenges for stable production. Forming a uniform dielectric film on the surface of the electrodes is important for enhancing the withstand voltage. However, since electrodes made with high-capacitance tantalum powder contain extremely small internal pores, dielectric oxide films tend to develop imperfections.　　Panasonic Industry overcame these challenges by establishing proprietary technology to mold high-capacitance tantalum powder with uniform density, and by optimizing the film deposition process to create flawless dielectric films. This enabled the development of two new models that combine an ultra-high withstand voltage and high capacitance, meeting the USB-C high-output power delivery requirements in a 3 mm low-profile package.Cross-sectional view of POSCAP and enlarged view of the inside of the electrode body　　2. Lineup of USB-PD 3.1-compliant models rated at 50 V and 63 V　　Until now, Panasonic Industry’s POSCAP lineup extended only up to 35 V, with no models compatible with USB-PD 3.1, which extends the rated voltage specification to 36 V (180 W) and 48 V (240 W). The two new models, rated at 50 V and 63 V, each achieve a high capacitance of 22 μF or higher in a package with the industry's lowest profile of 3 mm. The full lineup provides flexibility to meet diverse applications and equipment specifications.　　3. Contributes to reduced material usage lower environmental impact through low-profile design　　Compared to the industry standard size*3, the new models reduce volume by 25%, contributing to a lower environmental impact through reduced material usage.　　*3 Comparison with the industry standard size (7.3 mm × 4.3 mm × 4 mm) of conductive polymer tantalum solid capacitors used in USB-PD 3.1 compliant power suppliesApplications:　　Voltage stabilization and noise reduction of USB-PD 3.1-compliant power supplies for laptops, displays, and peripheral equipment　　Arc discharge[2] countermeasures for USB-PD 3.1-compliant connectors　　Specifications:　　Life: 2,000 hours at 105°C; guaranteed operating temperature range: -55°C to 105°C　　Ripple current[3]: 100 kHz, 105°C　　ESR[4]: 100 kHz, 20°C　　*4 Product dimensional tolerance:　　Length (L): ±0.3 mm; Width (W): ±0.2 mm; Height (H): ±0.2 mmTerm descriptions:　　[1] USB-PD　　The power delivery standards established by the standard-setting organization USB Implementers Forum, Inc. (USB-IF).
