Description

The LDFM is a fast, very low drop linear regulator

which operates from an input supply voltage in

the range of 2.5 V to 16 V.

It is available in fixed and adjustable output

voltage versions, from 0.8 V to 12 V.

The LDFM features high output precision, very

low dropout voltage, low noise, and low quiescent

current, therefore suitable for low voltage

microprocessors and memory applications.

Enable logic control pin and Power Good output

are featured on PPAK/DFN packages.

Current and thermal protection are provided.
