Description and Introduction

150mA High PSRR, Low Noise μCap CMOS LDO # **MIC5252-2.85BM5: A High-Performance LDO Regulator for Precision Applications**  

The **MIC5252-2.85BM5** is a high-performance, low-dropout (LDO) voltage regulator designed to deliver stable and efficient power management in a compact footprint. With a fixed output voltage of **2.85V**, this regulator is ideal for applications requiring precise voltage regulation, such as portable electronics, IoT devices, and embedded systems.  

Engineered for reliability, the MIC5252-2.85BM5 offers a low dropout voltage of just **250mV at 150mA**, ensuring efficient operation even when the input voltage is close to the output level. Its ultra-low quiescent current of **45µA (typical)** makes it an excellent choice for battery-powered devices, extending operational life while minimizing power consumption.  

The device features **fast transient response**, maintaining stable output under dynamic load conditions. With built-in protection mechanisms including **thermal shutdown and current limiting**, the MIC5252-2.85BM5 safeguards against overheating and excessive current draw, enhancing system durability.  

Housed in a **space-saving SOT-23-5 package**, this LDO regulator is optimized for compact PCB designs while delivering a robust **150mA output current**. Its low noise performance and high power supply rejection ratio (PSRR) ensure clean, ripple-free power, making it suitable for noise-sensitive applications such as RF circuits and analog sensors.  

Whether used in industrial control systems, medical devices, or consumer electronics, the **MIC5252-2.85BM5** provides a dependable power solution with minimal external components, simplifying design integration. Its combination of efficiency, precision, and protection features makes it a preferred choice for engineers seeking a high-quality voltage regulator for demanding applications.
