Description

The APL5523 is a dual low dropout regulator with output 1 with 3.3V/0.5A and output2 with 1.8V/0.3A output capability . In order to obtain lower dropout voltage and faster transient response, which is critical  for low voltage applications, the APL5223 has been optimized. The dropout voltages are guaranteed at 0.6V at 0.5A for output1 and 0.9V at 0.3A f or output 2.
