产品概述
描述
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.
