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 APL5546 maintains a low supply current.  Other features  include,  thermal-shutdown  protecti on,  current limit  protection  to  ensure  specified  output  current.
