General Description
Typical Application
AF1117A is a series of low dropout three-terminal
regulators with a dropout of 1.3V at 1.0A load current.
AF1117A features a very low standby current 2mA
compared to 5mA of competitor.
Other than a fixed version, Vout = 1.2V, 1.8V, 2.5V, 3.3V,
5V, and 12V, AF1117A has an adjustable version, which can
provide an output voltage from 1.25 to 12V with only two
external resistors.
AF1117A offers thermal shut down and current limit
functions, to assure the stability of chip and power system.
And it uses trimming technique toguarantee output voltage
accuracy within 2%. Other output voltage accuracy can be
customized on demand, such as 1%.AF1117A is available
in SOT-223, TO-252 power package.
