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
50
μ
V
RMS
with the addition of an external 0.1
μ
F bypass
capacitor in BP pin and typical dropout voltage is only
210mV at 900mA loading. Designed for use in bat-
tery-powered system, the low 50
μ
A quiescent cur-
rent makes it an ideal choice.

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 con-
trolled short-circuit current. The APL5901/2 regulator
come in a miniature SOT-89, SOT-89-5, SOT-223, SO-
8, TO-252 and TO-252-5 packages.
