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%.
