Overview

LDO40L is a 400mA low-dropout regulator designed for demanding automotive environments. Its low quiescent current makes it well-suited for battery-connected applications, a feature particularly critical in scenarios where electronic modules remain active after ignition-off. The LDO40L integrates protection features such as current limiting and thermal shutdown. The extended input voltage range, low dropout, and low quiescent current characteristics also make it suitable for low-power industrial and consumer applications.

Applications

  • Automotive applications
  • Body control modules
  • Instrument clusters
  • Automotive LED lighting
  • Low-power industrial applications
  • Low-power consumer applications
