Description:
The APL5546 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, 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 device maintains a low supply current. Other features include, thermal-shutdown protecti on, current limit protection to ensure specified output current. The device come in miniature SOP-8 and SOP-8-P packages.
