General Description
The APL5308/9 series are micropower, low dropout lin-
ear regulators, which operate from 2.7V to 6V input volt-
age and deliver up to 300mA. Typical dropout voltage
is only 400mV at 300mA loading. Designed for use in
battery-powered system, the low 60µA quiescent cur-
rent makes it an ideal choice. Design with an internal P-
channel MOSFET pass transistor, the APL5308/9 maintain
a low supply current, independent of the load current and
dropout voltage. Other features include thermal-shut-
down protection current limit protection to ensure
specified output current and controlled short-circuit
current. The APL5308/9 regulators come in a minia-
ture SOT-23-3, SOT-23-5, and SOT-89 packages.
