General
Description
The APL5538 is a dual-channel regulator with reset function (specific voltage onitoring), and internal delay 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 APL-5538 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.
