CM1117 Datasheet, PDF (1/6 Pages) Champion Microelectronic Corp. – 1A LOW DROPOUT VOLTAGE REGULATOR

CM1117
1A LOW DROPOUT VOLTAGE REGULATOR
GENERAL DESCRIPTION
FEATURES
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%.
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
