The APL5538 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 300mA. VOUT1 typical dropout voltage is 350mV at 300mA loading and VOUT2 typical dropout voltage is 350mV at 300mA loading. Design with an internal Pchannel MOSFET pass transistor, th.
