Features
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 regu-
lators come in a miniature SOT-23, SOT-23-5 and
SOT-89 packages.
