Features

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 60

µA 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.
