Applications

General Description

The APL5708R series are micropower, low dropout
linear regulators, which operate from 2.7V to 6V in­put voltage and deliver up to 700mA. Typical dropout
voltage is only 700mV at 700mA 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
APL5708R 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 APL5708R regu-

lators come in a miniature SOT-223 package.
