ACE501
250mA CMOS Low Dropout Voltage Low consumption Regulator
Description
ACE501 series is a group of positive voltage output, low power consumption, low dropout voltage, three
terminal regulator. It can provide 250mA output current when input / output voltage differential drops to
400mV (Vin=4.0V. Vout=3.0V).The very low power consumption of ACE501 (lq=3.0uA) can greatly
improve natural life of batteries.
ACE501 can provide output value in the range of 1.2V~6.0V in 0.1V steps. It also can customized on
command.
ACE501 includes high accuracy voltage reference, error amplifier, current limit circuit and output driver
module.
ACE501 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%.
