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
1V 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
Load Regulation: 0.4% Max
Fast Transient Response
Thermal Protection
SOT-223 and TO-252 package available
