General  Description :

The APL5523 is a dual low dropout regulator with output1 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 for output 2. 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.


1. Fixed  Output Voltage :
(1)  VOUT1=3.3V/500mA

(2) Output  2  Dropout  V oltage : 0.9V  (at 300mA)
3. Stable with 4.7mF Output Capacitor(at VOUT1
4. Stable with 2.2mF Output Capacitor(at VOUT2)
5. Built-In Thermal Protection
6. Built-In Current-Limit Protection
7. Fast Transient Response
8. Short Setting Time
9. SOP-8 and SOP-8P Packages Available
10. Lead Free and Green Devices Available(RoHS  Compliant)
