DESCRIPTION
The AMC1112 of positive 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.
The AMC1112 offers current limiting and thermal
protection. The on chip trimming adjusts the reference
voltage accuracy to 1%.
