GS1117AX datasheet

Description :

The GS1117A is a low dropout three-terminal regulator with 1A output current capability. In order to obtain lower dropout voltage and fast transient response, which is critical for low voltage applications.

Current limit is trimmed to ensure specified output current and controlled short circuit current. On-chip thermal limiting provides protection against any combination of overload that would create excessive junction temperatures.
