General Description
The APL5151/2/3/4 is micropower, low noise, low
dropout linear regulator. Operate from 3V to 6V input
voltage 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
current 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 specified output current and controlled short-
circuit current. The APL5151/2/3/4 regulators come in
a miniature SOT-23-5 package.
