产品概要
描述
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 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 DFN package.
Current and thermal protection are provided.
