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.

Input voltage from 2.6 to 16 V

Very low-dropout voltage (500 mV max. at 1 A load)

Low quiescent current (200 μA typ. @ 1 A load)

Available in 1% precision in PPAK and DFN6 packages, 2% in DPAK

1 A guaranteed output current

Wide range of output voltages available on request: adjustable from 0.8 Vfixed up to

12 V in 100 mV steps

Logic-controlled electronic shutdown

Power Good (PPAK and DFN packages)

Fast dynamic response to line and load changes

Internal current and thermal protections

Temperature range: -40 °C to 125 °C
