Application hints:
Note1: Input capacitor (Cin=1uF) is recommended in all application circuit.
Note2: Output capacitor (Cout=1uF/2.2uF) is recommended in all application to assure the stability of
circuit.
Explanation：
ACE505 series is a group of positive voltage output, low noise, low power consumption, low dropout
voltage regulator.
ACE505 can provide output value in the range of 1.2V~5.0V every 0.1V step. It also can be customized
on command.
ACE505 includes high accuracy voltage reference, error amplifier, current limit circuit and output driver
module.
