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.
TheAPL5151/2/3/4 regulatorscome ina miniatureSOT-
23-5 package.
