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 handheld and 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, over temperature shutdown, ultra-low-noise capability (SO-8 and TO-263-5 versions) and availability in thermally efficient packaging. This is available in adjustable or fixed output voltages.
