The MIC5209BU 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 MIC5209BU 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 MIC5209BU is available in adjustable or fixed output voltages.
