Features

General Description

The APL5101/2 are micro-power, ultra low dropout

linear regulator, which operate from 2V to 6V input

voltage and deliver up to 150mA. Typical dropout

voltage is only 200mV at 150mA loading. Designed

for use in battery-powered system, the low 4

µA

quiescent current makes it an ideal choice. Design

with an internal P-channel MOSFET pass transistor,

the APL5101/2 maintain a low supply current,

independent of the load current and dropout voltage.

Other features include thermal-shutdown protection

and current limit protection to ensure specified

output current and controlled short-circuit current.

The APL5101/2 regulator come in a miniature SOT-23,

SOT-23-5 and SOT-89 packages.
