AF1117 - Low Dropout Positive Voltage Regulator

Download the AF1117 datasheet PDF. This datasheet also covers the AF1117-Alfa variant, as both devices belong to the same low dropout positive voltage regulator family and are provided as variant models within a single manufacturer datasheet.

General Description

The AF1117 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%.

Key Features

  • Adjustable Output.
  • Output Current of 1A.

Alfa-MOS Technology AF1117 1A / 20V Low Dropout Positive Voltage Regulator General Description The AF1117 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.
