Product Details
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.
