ACE577C
40V 150mA Low Consumption Linear Regulator
Description
ACE577C series is a group of positive voltage output, low power consumption, low dropout voltage
regulator. It can provide 150mA output current when input / output voltage differential drops to 400mV
(Vout = 5V), and it also provides fold back short-circuit protection, thermal protection and output current
limit function. The very low power consumption of ACE577C (Iq = 2.5uA) can greatly improve natural life
of batteries.
ACE577C can provide output value in the range of 1.2V~5.0V in 0.1V steps. It also can customize on
command.
ACE577C includes high accuracy voltage reference, error amplifier, and current limit circuit and output
driver module.
ACE577C has well load transient response and good temperature characteristic, And it uses trimming
technique to guarantee output voltage accuracy within±2%.
