ACE555
300mA High PSRR, Linear Regulator
Description
ACE555 series are a group of positive voltage output, low power consumption, low dropout voltage
regulators.
ACE555 can provide output value in the range of 1.0V~4.5V every 0.1V step. It also can be customized
on command. ACE555 can also work under a wide input voltage ranging from 1.5V to 6V.
ACE555 includes high accuracy voltage reference, error amplifier, current limit circuit and output driver
module.
ACE555 has excellent load and line transient response and good temperature characteristics, which can
assure the stability of chip and power system. And it uses trimming technique to guarantee output voltage
accuracy within ±1%、±2%.
