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.
