The APL5308/9 series are micropower, low dropout
linear regulators, which operate from 2.7V to 6V in-
put 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 qui-
escent current makes it an ideal choice. Design with
an internal P-channel MOSFET pass transistor, the
APL5308/9 maintain a low supply current, indepen-
dent 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.
