Description
ACE51117C is a series of low dropout three-terminal regulators with a dropout of 1.3V at 800mA load
current. ACE51117C features a low standby current 2mA.
Other than a fixed version (Vout = 1.2V, 1.8V, 2.5V, 3.3V and 5V), ACE51117C has an adjustable version,
which can provide an output voltage from 1.25 to 5V with only two external resistors.
ACE51117C 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.
ACE51117C is available in SOT89-3 power packages.
