Detection to Reset Release

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
500mA. VOUT1 typical dropout voltage is 550mV at
500mA loading and VOUT2 typical dropout voltage is
630mV at 500mA loading. Design with an internal P­channel 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.
