Features
General Description
The APL5151/2/3/4 is micropower, low noise, low drop-
out linear regulator. Operate from 3V to 6V input volt-
age and deliver up to 150mA. Typical output noise is
just 60uV
RMS
with the addition of an external 0.33uF
bypass capacitor in BP pin and typical dropout voltage
is only 220mV at 150mA loading. Designed for use in
battery-powered system, the low 50uA quiescent cur-
rent makes it an ideal choice. Design with an internal
P-channel MOSFET pass transistor, the APL5151/2/
3/4 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 speci-
fied output current and controlled short-circuit current.
The APL5151/2/3/4 regulators come in a miniature SOT-
23-5 package.

Marking Information
The last character "X" in the marking is for data code.
Note: ANPEC lead-free products contain molding compounds/die attach materials and 100% matte in plate termina-
tion finish; which are fully compliant with RoHS and compatible with both SnPb and lead-free soldiering operations.
ANPEC lead-free products meet or exceed the lead-free requirements of IPC/JEDEC J STD-020C for MSL classifica-
tion at lead-free peak reflow temperature.
