MIC5209-3.3YS Product Details

The MIC5209-3.3YS is an efficient linear voltage regulator with very low dropout voltage, typically 10mV at light loads and less than 500mV at full load, with better than 1% output voltage accuracy.

Designed especially for hand-held, battery-powered devices, the MIC5209-3.3YS features low ground current to help prolong battery life. An enable/shutdown pin on SOIC-8 and DDPAK versions can further improve battery life with near-zero shutdown current.

Key features include reversed-battery protection, current limiting, overtemperature shutdown, ultra-low-noise capability (SOIC-8 and DDPAK versions), and availability in thermally efficient packaging. The MIC5209-3.3YS is available in adjustable or fixed output voltages.



  • Output voltage range: 1.8V to 15V
  • Meets Intel® Slot 1 and Slot 2 requirements
  • Guaranteed 500mA output over the full operating temperature range
  • Low 500mV maximum dropout voltage at full load
  • Extremely tight load and line regulation
  • Thermally efficient surface-mount package
  • Low temperature coefficient
  • Current and thermal limiting
  • Reversed battery protection
  • No-load stability
  • 1% output accuracy
  • Ultra-low noise capability in SOIC-8 and DDPAK
  • Ultra-small 3mm x 3mm DFN package
