MIC5331 - Micro-Power High Performance Dual 300mA ULDO

General Description

The MIC5331 is a tiny dual low quiescent current LDO ideal for applications that are power sensitive.

The MIC5331 integrates two high performance, 300 mA LDOs into a tiny 2 mm x 2 mm Thin DFN package, which occupies less PC board area than a single SOT-23 package.

Key Features

  • 2.3V to 5.5V Input Voltage Range.
  • 300 mA Output Current per LDO.
  • Low Quiescent Current: 25 µA per LDO.
  • High PSRR: >65 dB on Each LDO.
  • Stable with 1 µF Ceramic Output Capacitors.
  • Tiny 8-pin 2 mm x 2 mm Thin DFN Package.
  • Ultra-Low Dropout Voltage: 120 mV @ 300 mA.
  • Low Output Voltage Noise: 50 µVRMS.
  • Thermal Shutdown Protection.
  • Current-Limit Protection.
