General Description
The APL5901/2 is micropower, low noise, low dropout linear regulator. Operate from 2.7V to 6V input voltage and deliver up to 900m A. 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 210m V at 900m A loading. Designed for use in battery-powered system, the low 50µA quiescent current makes it an ideal choice.
