General Description
The APL5546 is a dual-channel regulator with reset
function (specific voltage monitoring), and internal de-
lay circuit, set to detect 3.9V or 4.2V. Maximum in-
put voltage is 6V, and both output1 and output2 can
deliver up to 500mA. The typical dropout voltage of
both channel is 500mV at 500mA loading. Design
with an internal P-channel MOSFET pass transistor,
the APL5546 maintains a low supply current. Other
features include, thermal-shutdown protection, current
limit protection to ensure specified output current. The
APL5546 come in miniature SOP-8 and SOP-8-P
packages.
