APL5521 - 3.3V/500mA and 2.5V/300mA Linear Regulator

Datasheet Summary

Description

The APL5521 is a dual low dropout regulator with output 1 with 3.3V/0.5A and output2 with 2.5V/0.3A output capability.

In order to obtain lower dropout voltage and faster transient response, which is critical for low voltage applications, the APL5221 has been optimized.

Features

  • Fixed Output Voltage : VOUT1=3.3V/500mA VOUT2=2.5V/300mA.
  • Low Dropout Voltage (defined as the minimum www. DataSheet4U. com input/output voltage difference): Output 1 Dropout Voltage : 1.25V (at 500mA) Output 2 Dropout Voltage : 1.2V (at 300mA).
  • Stable with 10uF Output Capacitor(at VOUT1) Stable with 10uF Output Capacitor(at VOUT2).
  • No Protection Diodes Needed.
  • Built in Thermal Protection Built in Current Limit Protection.
