LD56020 - Low input voltage 200 mA ultra low dropout linear regulator


Low input voltage 200 mA ultra low dropout linear regulator

The LD56020 is a high accuracy voltage regulator which provides 0.2 A of current. It is available in CSP 0.65 x 0.65 mm² and SOT23-5L packages, allowing the maximum space saving.

The device is stabilized with a small ceramic capacitor on input and output. The ultra-low drop, low quiescent current and short-circuit current foldback make the LD56020 suitable for low power battery-operated applications.

Key features

  • Input voltage range 1.1 V to 5.5 V
  • Ultra-low dropout voltage (190 mV max. at 200 mA load)
  • Low ground current (18 μA typ. at no load)
  • 200 mA guaranteed output current
  • Ultra-low output noise: 8.8 µVRMS (10 Hz to 100 kHz)
  • 50 mV output voltage steps (available on request) from 0.6 V to 4.0 V
  • Logic-controlled electronic shutdown
  • Thermal shutdown
