Overview

The MD53RXX series are positive-voltage LDO regulators developed using CMOS technology, featuring high-accuracy output voltage and ultra-low quiescent current. The built-in low on-resistance transistor enables low dropout voltage. Maximum operating voltage up to 10V, suitable for applications requiring higher voltage ratings. Output short-circuit protection is integrated to prevent device damage.

Applications

  • Regulated power supply for battery-powered devices
  • Regulated power supply for communication equipment
  • Regulated power supply for home appliances and toys
  • Regulated power supply for mobile phones
  • Regulated power supply for portable medical instruments

Key features

  • High output voltage accuracy: ±2%
  • Output current: 500mA typical
  • Low input-output voltage differential: 1.5mV typical at IOUT=1mA
  • Ultra-low quiescent current: 25uA typical
  • Low output voltage temperature drift: 50ppm/°C typical
  • Input voltage tolerance: maintains regulated output up to 10V
  • Output short-circuit protection: short-circuit current 50mA
  • High ripple rejection ratio: 65dB typical
