? General Description

AF1117 is a series of low dropout three-terminal

regulators with a dropout of 1.3V at 1A load current.

AF1117 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, AF1117 has an adjustable version, which can

provide an output voltage from 1.25 to 12V with only two

external resistors.

AF1117 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%.AF1117 is available in

SOT-223, TO-252 power package.
