ACE1117H
1A Bipolar Linear Regulator
Description
ACE1117H is a series of low dropout three-terminal regulators with a dropout of 1.3V at 1A load current.
ACE1117H features a low standby current 2mA.
Other than a fixed version (Vout = 1.2V, 1.8V, 2.5V, 3.3V, 5V, and 12V), ACE1117H has an adjustable
version, which can provide an output voltage from 1.25 to 12V with only two external resistors.
ACE1117H offers thermal shut down and current limit functions, to assure stability of chip and power
system. Trimming technique is used to guarantee output voltage accuracy within ±2%. Other output
voltage accuracy such as ±1% can be customized on demand.
