Detection to Reset Release
The APL5538 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, output1 and output2 deliver up to
300mA. VOUT1 typical dropout voltage is 350mV at
300mA loading and VOUT2 typical dropout voltage is
350mV at 300mA loading. Design with an internal P-
channel MOSFET pass transistor, the APL5538 main-
tains a low supply current. Other features include,
thermal-shutdown protection, current limit protection
to ensure specified output current. The APL5538 come
in miniature SOP-8 and SOP-8-P packages.
