Features

General Description

The APL5525/6 is a dual-channel regulator with reset

function (specific voltage monitoring), and internal

delay circuit, set to detect 3.9V or 4.2V. Maximum

input voltage is 6V, output1 and output2 deliver up to

630mV at 500mA loading. Design with an internal P-

channel MOSFET pass transistor, the APL5525/6

maintains a low supply current. Other features include,

thermal-shutdown protection, current limit protection

to ensure specified output current. The APL5525/6

come in miniature SOP-8 and SOP-8-P packages.
