Description

ACE1117C is a series of low dropout three-terminal regulators with a dropout of 1.3V at 1A load current.

ACE1117C features a very low standby current 2mA compared to 5mA of competitor.

Other than a fixed version Vout＝1.2V,1.8V,2.5V,2.85V,3.3V,5V and 12V, ACE1117C has an adjustable

version, which can provide an output voltage from 1.25 to 12V with only two external resistors.

ACE1117C offers thermal shut down and current limit functions, to assure the stability of chip and power

system. And it uses trimming technique to guarantee output voltage accuracy within ±2%.Other output

voltage accuracy can be customized on command, such as ±1%.
