ACE507C

ACE507C
200mA Low Consumption Linear Regulator
Description
ACE507C 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 430mVVout=2.8V), The very low power consumption of ACE507C(Iq=1.0uA)can greatly improve
natural life of batteries.
ACE507C can provide output value in the range of 1.1V~5.5V in 0.1V steps. It also can customized on
command.
ACE507C includes high accuracy voltage reference, error amplifier, current limit circuit and output driver
module.
ACE507C has well load transient response and good temperature characteristic, And it uses trimming
technique to guarantee output voltage accuracy within±2%.

ACE507C
200mA Low Consumption Linear Regulator
Explanation:
ACE507C 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 200mA.
ACE507C 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 ACE507C’s temperature
coefficient within 100ppm/℃.
