The LDF is a fast, very low drop linear regulator

which operates from an input supply voltage in

the range of 2.6 V to 16 V.

It is available in fixed and adjustable output

voltage versions, from 0.8 V to 12 V.

The LDF features are: 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.
