DESCRIPTION
FEATURES
The AMC1117 series of positive adjustable and fixed
regulators is 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.
Output current of 1A typical
Three-terminal adjustable or fixed 1.5V, 1.8V,
2.5V, 3.3V, 5.0V outputs
Low dropout of typical 800mV
Thermal protection built in
Typical 0.015% line regulation
Typical 0.01% load regulation
The AMC1117 offers current limiting and thermal
protection. The on chip trimming adjusts the reference
voltage accuracy to 1%.
Fast transient response
Available in SOT-223 and TO-252 packages
Pin assignment identical to earlier LT1117 series.
