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 con-
trolled short-circuit current. The APL5501/2/3 regu-
lator comes in a miniature SOT-23-5, SOT-89, SOT-
89-5, SOT-223, SO-8, TO-252 and TO-252-5
packages.

General Description
The APL5501/2/3 is micropower, low noise, low drop-
out 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 volt-
age is only 170mV at 500mA loading . Designed for
use in battery-powered system, the low 50uA quies-
cent current makes it an ideal choice.
