Features

•Rapid-control architecture enables operation witha high input/output voltage ratio (e.g., VIN = 28Vand VOUT = 0.8V) and small output capacitance

•Adjustable output voltage from 0.8V to 5.5V

•Universally compatible with most outputcapacitors—stable with zero to high ESR

•Power good (PG) output

•Foldback current limiting and “hiccup” modeshort-circuit protection

•Safe start-up into pre-biased loads

Available Support
