Description

The AMC1117 series of positive adjustable and fixed regulators is designed to provide 1A for applications requiring high efficiency. All internal circuitry is designed to operated down to 800mV input to output differential and the dropout voltage is fully specified as a function of load current.

The AMC1117 offers current limiting and thermal protection. The on chip trimming adjusts the reference voltage accuracy to 1%.
