Datasheet
Descriptions
The S1117A and S1117 series of positive adjustable and fixed regulators are designed to
provide 1A with higher efficiency than currently available devices. All internal circuitry is
designed to operate down to 1.3V input to output differential. On-Chip trimming adjusts
reference Voltage to 2%
