General Description

The AF1117A series of positive adjustable

regulators are designed to provide 1A with high

efficiency. All internal circuitry is designed to

operate down to 1.4V input to output differential.

On-chip trimming adjusts the reference voltage

to 1%. Current limit the typical value of 1.5A allows

to minimize the stress on both the regulator and

the power source circuitry under overload

conditions.
