General Description
The APL5522 is a dual low dropout
regulator with output 1 with 3.3V/0.5A and output2 with 2.5V/0.5A output capability. In order to obtain lower dropout voltage and faster transient response, which is critical for low voltage applications, the APL5522 has been optimized. VOUT1 typical dropout voltage is 550mV at 500mA loading and VOUT2 typical dropout voltage is 630mV at 500mA loading. Current limit is trimmed to ensure specified output current and controlled short-circuit current. On-chip thermal limiting provides protection against any combination of overload that would create excessive junction temperatures. The APL5522
regulator comes in a SOP-8 and SOP-8P packages.
