ACE525C
300mA High PSRR, Linear Regulator
Description
ACE525C series are a group of positive voltage output, low power consumption, low dropout voltage
regulators.
ACE525C can provide output value in the range of 1.0V~4.5V every 0.1V step. It also can be customized
on command. ACE525C can also work under a wide input voltage ranging from 1.5V to 6V.
ACE525C includes high accuracy voltage reference, error amplifier, current limit circuit and output driver
module.
ACE525C 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 ±2%.
