Features

General Description

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

linear regulators, which operate from 2V to 6V input volt-

age and deliver up to 150mA. Typical dropout voltage is

only 200mV at 150mA loading. Designed for use in bat-

tery-powered system, the low 4

µA quiescent current

makes it an ideal choice. Design with an internal P-chan-

nel 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 regu-

lators come in a miniature SOT-23, SOT-23-5, and SOT-

89 packages.
