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 APL5501/2/3 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 APL5501/2/3 regulator comes in a miniature SOT-23-5, SOT-89, SOT89-5, SOT-223, SO-8, TO-252 and TO-252-5
packages.

General Description
The APL5501/2/3 is micropower, low noise, low dropout linear regulator. Operate from 2.7V to 6V input
voltage and deliver up to 500mA. 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 170mV at 500mA loading . Designed for
use in battery-powered system, the low 50uA quiescent current makes it an ideal choice.
