ACE518C

1A Ultra-Low Vin Low Dropout Voltage Linear Regulator

VER 1.1

Electrical Characteristics

Test Conditions: CIN=4.7uF,COUT=4.7uF,TA=25℃, unless otherwise specified

Note: *Iout=500mA@Vout=1.2V

**The maximum power rating of each package is a constant, so along with the change of ILOAD, the VDD-VOUT

should be controlled to a certain range to ensure the normal operation.
