General Description

The CM1117 series of adjustable and fixed voltage regulators are 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 CM1117 offers current limiting and thermal protection. The on chip trimming adjusts the reference voltage accuracy to 1%.
