MICROCHIP MIC5209-3.3YS-TR

The MIC5209 is an efficient linear voltage regulator with very low dropout voltage, typically 10 mV at light loads and less than 500 mV 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 the 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 is available in thermally efficient packaging. The MIC5209 is available in adjustable or fixed output voltages.
