APL5902 Overview
The APL5901/2 is micropower, low noise, low dropout linear regulator. Operate from 2.7V to 6V input voltage and deliver up to 900mA. Typical output noise is just 50µVRMS with the addition of an external 0.1µF bypass capacitor in BP pin and typical dropout voltage is only 210mV at 900mA loading.
