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.
