Overview

MD51XX is a highly accurate low dropout voltage regulator (LDO) manufactured in CMOS processes. It can deliver up to 300mA of current while consuming only 0.5uA 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.

Applications

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

Key features

  • Ultra-low Quiescent Current: 500nA
  • Highly Accurate: ±2%
  • Dropout Voltage: 60mV÷Iour = 100mA
  • Maximum Output Current: 300mA
  • Input Voltage Range: 1.4V~7.0V
  • Temperature Stability: ±50ppm/°C
  • ON/OFF Logic = Enable High
  • Standby Current: 10nA
  • COUT Discharge Circuit when EN Disable is Active
  • Protections Circuits: Current Limiter, Short Circuit, Foldback
  • Output Capacitor: Low ESR Ceramic Capacitor Compatible
