ME6301-N Power Management IC, CMOS Type LDO Linear Regulator, Low Noise, High PSRR, High Accuracy, 1.2–5.0V Output, 250mA, SOT23-5 Package

The ME6301-N is a high-performance Power Management IC designed as a CMOS type Low Dropout (LDO) linear regulator for noise-sensitive and battery-powered applications. It supports a maximum input voltage of 6.5V and provides fixed output voltages ranging from 1.2V to 5.0V with ±1% high accuracy.

Featuring ultra-low output noise and an exceptional PSRR of 98dB @ 1kHz, the ME6301-N effectively suppresses power supply ripple and noise, making it ideal for RF modules, analog circuits, and precision digital systems. Its low quiescent current of 18µA ensures excellent power efficiency, while delivering up to 250mA output current.

The device is housed in a compact SOT23-5 package, enabling easy integration into space-constrained PCB layouts.
