ACE515C
300mA High PSRR, Fast Response Linear Regulator
Description
ACE515C series is a group of positive voltage output, low power consumption, low dropout voltage
regulator.
ACE515C can provide output value in the range of 1.0V~4.5V every 0.1V step. It also can be customized
on command. ACE515C can also work under a wide input voltage ranging from 1.5V to 6V.
ACE515C includes high accuracy voltage reference, error amplifier, current limit circuit and output driver
module with discharge capability.
ACE515C 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%.
