General Description
The APL5308/9 series are micropower, low dropout
linear regulators, which operate from 2.7V to 6V input
voltage 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 current 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-shutdown protection current limit
protection to ensure specified output current and
controlled short-circuit current. The APL5308/9
regulators come in a miniature SOT23-3, SOT23-5
and SOT89 packages.
