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%.
FEATURES
Three Terminal Adjustable or Fixed Voltages: 1.8V, 2.5V,
3.3V, and adjustable.
Output Current of 1A
Low dropout voltage: 1V Typ.
Line Regulation: 0.2% Max
