Overview

MD52XX is ultra-low power consumption low dropout voltage regulator (LDO) manufactured in CMOS processes. It can deliver up to 500mA of current while consuming only 0.6μA 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 MD52XX 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.

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: 0.6μA
  • Highly Accurate: ±2%
  • Dropout Voltage: 230mV@lour = 500mA
  • Maximum Output Current: 500mA
  • Input Voltage Range: 2.2V ~ 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
