ACE523C
250mA Low consumption Linear Regulator
Description
ACE523C series is a group of positive voltage output, low power consumption, low dropout voltage,
three terminal regulator. It can provide 200mA output current when input / output voltage differential drops
to 418mV (Vout= 3.3V), And it also provides foldback short-circuit protection and output current limit
function. The very low power consumption of ACE523C (Iq=3uA)can greatly improve natural life of
batteries.
ACE523C can provide output value in the range of 1.2V~5.0V in 0.1V steps. It also can customized on
command.
ACE523C includes high accuracy voltage reference, error amplifier, current limit circuit and output driver
module.
ACE523C has well load transient response and good temperature characteristic, And it uses trimming
technique to guarantee output voltage accuracy within±2%.
