Benefits

• Ultra-light load efficiency – up to 80 at 10mA

• Up to 95 efficiency

• Feedback reference accuracy as high as ±1

Features

• Rapid-control architecture enables operation with

a high input/output voltage ratio (e.g., VIN = 19V

and VOUT = 0.8V) and small output capacitance

• Adjustable output voltage from 0.8V to 5.5V

• Universally compatible with most output

capacitors—stable with zero to high ESR

• Power good (PG) output

• Foldback current limiting and “hiccup” mode

short-circuit protection

• Safe start-up into pre-biased loads

Available Support
