The MIC5209 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 features low ground current to help prolong battery life. An enable/shutdown pin on SO-8 and TO-263-5 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 (SO-8 and TO-263-5 versions), and availability in thermally-efficient packaging. The MIC5209 is available in adjustable or fixed output voltages.Output voltage range: 1.8V - 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 SO-8 and TO-263-5 Ultra-small 3mm × 3mm DFN package
