Overview

MD85XX is a high voltage (up to 40V) ultra-low quiescent current low dropout voltage regulator (LDO) manufactured in CMOS processes. It can deliver up to 300mA of current while consuming only 1.5uA of quiescent current. It consists of a reference voltage generator, an error amplifier, a current foldback circuit, and a phase compensation circuit plus a driver transistor. The MD85XX is designed specifically for applications where very-low IQ is a critical parameter. This device maintains low quiescent current consumption even in dropout mode to further increase the battery life. When in shutdown or disabled mode, the device consumes less than 100-nA IQ even with input voltage of 40V that helps increase the shelf life of the battery.

Applications

  • Smart wearer
  • Long-life battery-powered devices
  • Portable mobile devices, such as mobile phones, cameras, and so on
  • Wireless communication equipment

Key features
