APL5551 Datasheet | Anpec Electronics

Features - - .. General Description The APL5551 is a dual-channel regulator with reset function (specific voltage monitoring), and internal delay circuit, set to detect 3.9V. Maximum input voltage is 6V, and both output1 and output2 can deliver up to 450m A. The typical dropout voltage of both channel is 500m V at 500m A loading. Design with an internal P-channel MOSFET pass transistor, the APL5551 maintains a low supply current. Other features include, thermal-shutdown protection, current limit protection to ensure specified output current. The APL5551 es in miniature SOP-8 and SOP-8-P packages.
