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.

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.

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). With the launch of USB-PD 3.1 in 2021, USB Type-C cables and connectors can now deliver up to 240 W of power, supporting a wide range of applications—from smartphones and laptops to larger equipment such as monitors.　　[2] Arc discharge　　An electric spark or discharge phenomenon that occurs when a high current flows at low voltage in electrical circuits.　　[3] Ripple current　　When a voltage fluctuation is applied to a capacitor, a corresponding charging or discharging current flows through the capacitor. The current applied to this capacitor is referred to as a ripple current. The higher the ripple current, the higher the allowable current.　　[4] ESR (Equivalent Series Resistance)　　Represents the value of an internal resistance component that can cause heat generation. Capacitors with lower ESR allow higher ripple currents and provide excellent noise absorption.
