ANPEC reserves the right to make changes to improve reliability or manufacturability without notice, and advise customers to obtain the latest version of relevant information to verify before placing orders.
Features
Design with an internal P-channel MOSFET pass transistor, the APL5901/2 maintains a low supply current, independent of the load current and dropout voltage. Other features include reverse current protection, thermal-shutdown protection, current limit protection to ensure specified output current and con­trolled short-circuit current. The APL5901/2 regulator come in a miniature SOT-89, SOT-89-5, SOT-223, SO­8, TO-252 and TO-252-5 packages.

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 900mA. Typical output noise is just
50µV
RMS
with the addition of an external 0.1µF by­pass capacitor in BP pin and typical dropout voltage is only 210mV at 900mA loading. Designed for use in battery-powered system, the low 50µA quiescent cur­rent makes it an ideal choice.
