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.
  • 所有功能

    • Input voltage from 2.6 to 16 V
    • Very low-dropout voltage (500 mV max. at 1 A load)
    • Low quiescent current (200 μA typ. @ 1 A load)
    • Available in 1% precision in PPAK and DFN6 packages, 2% in DPAK
    • 1 A guaranteed output current
    • Wide range of output voltages available on request: adjustable from 0.8 V, fixed up to 12 V in 100 mV steps
    • Logic-controlled electronic shutdown
    • Power Good (PPAK and DFN packages)
    • Fast dynamic response to line and load changes
    • Internal current and thermal protections
    • Temperature range: -40 °C to 125 °C
