Technology
ACE502
400mA CMOS Low Dropout Voltage Low consumption Regulator
Description
ACE502 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
470mV（Vout=2.0V）。The very low power consumption of ACE502（Iq=7uA）can greatly improve natural
life of batteries.
ACE502 can provide output value in the range of 1.5V~6.0V in 0.1V steps. It also can customized on
command.
ACE502 includes high accuracy voltage reference, error amplifier, current limit circuit and output driver
module.
ACE502 has well load transient response and good temperature characteristic, which can assure the
stability of chip and power system. And it uses trimming technique to guarantee output voltage accuracy
within ±2%.
ACE502 is available in SOT-89-3、SOT-23-3、SOT-23-5 packages which is lead free，it also can available
in these packages with lead.
