ACE501
300mA 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 300mA output current when input / output voltage differential drops to
500mV (Vin=4.0V. Vout=3.0V).The very low power consumption of ACE501 (lq=1.0uA) can greatly
improve natural life of batteries.
ACE501 can provide output value in the range of 1.1V~5.5V 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%.

BLOCK DIAGRAM
EXPLANATION
ACE501 is a series of low dropout voltage and low power consumption three pins regulator. Its application
circuit is very simple, which only needs two outside capacitors. It is composed of these modules: high
Accuracy voltage reference, current limit circuit, error amplifier, output driver and power transistor.
Current Limit module can keep chip and power system away from danger when load current is more than
300mA.
ACE501 uses trimming technique to assure the accuracy of output value withing±2% at the same time,
temperature compensation is elaborately considered in this chip,which makes ACE501 temperature
coefficient within 100ppm/℃。
