ACE518C (VER1.1)

ACE518C
1A Ultra-Low Vin Low Dropout Voltage Linear Regulator
Description
ACE518C series are a group of positive voltage output, high precise, and low power consumption
voltage regulator. Voltages are selectable in 100Mv steps within a range of 1.2V to 5.0V. It also can be
customized on command.
ACE518C series have 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%.
