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 volt-
age is only 700mV at 700mA loading. Designed for
using 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
APL5708R 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 APL5708R regu-
lators come in a miniature SOT-223 package.
