Description

ACE528C series is a group of positive voltage output, low power consumption, low dropout voltage

regulator. It can provide 300mA output current when input / output voltage differential drops to 600mV

(Vout= 3.3V), and it also provides foldback short-circuit protection, thermal protection and output current

limit function. The very low power consumption of ACE528C (Iq=10uA) can greatly improve natural life of

batteries.

ACE528C can provide output value in the range of 1.2V~5.0V in 0.1V steps. It also can customize on

command.

ACE528C includes high accuracy voltage reference, error amplifier, and current limit circuit and output

driver module.

ACE528C has well load transient response and good temperature characteristic, and it uses trimming

technique to guarantee output voltage accuracy within±2%.
