 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.

Application hints:
Note 1:Input capacitor (Cin=1uF) is recommended in all application circuit. Tantalum capacitor is recommended.
Note 2:Output capacitor (Cout=1uF) is recommended in all application to assure the stability of circuit. Tantalum
capacitor is recommended. Explanation:
ACE502 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 400mA.
ACE502 uses trimming technique to assure the accuracy of output value within±2%, at the same time,
temperature compensated is elaborately considered in this chip, which makes ACE502 ’s temperature
coefficient within 50ppm/℃.
