产品概述
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 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.
