GENERAL DESCRIPTION
The CM1117F 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 1V input to output differential and the
dropout voltage is fully specified as a function of load current.
The CM1117F offers current limiting and thermal protection.
The on chip trimming adjusts the reference voltage accuracy
to2%.
