Features

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 60

µA 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.
