General Description
The APL5551 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, and both output1 and output2 can
deliver up to 450mA. The typical dropout voltage of
both channel is 500mV at 500mA loading. Design with
an internal P-channel MOSFET pass transistor, the
APL5551 maintains a low supply current. Other features
include, thermal-shutdown protection, current limit
protection to ensure specified output current. The
APL5551 comes in miniature SOP-8 and SOP-8-P
packages.
