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%.
