MIC5209-4.2YS Microchip

MIC5209 500 mA Low-Noise LDO Regulator Features General Description Output Voltage Range: 1.8V 15V The MIC5209 is an efficient linear voltage regulator with very low dropout voltage, typically 10 mV at light Slot 1 and Slot 2 Requirements Meets Intel loads and less than 500 mV at full load, with better than Guaranteed 500 mA Output Over the Full 1% output voltage accuracy. Operating Temperature Range Designed especially for hand-held, battery-powered Low 500 mV Maximum Dropout Voltage at Full devices, the MIC5209 features low ground current to Load help prolong battery life. An enable/shutdown pin on Extremely Tight Load and Line Regulation the SOIC-8 and DDPAK versions can further improve Thermally Efcient Surface-Mount Package battery life with near-zero shutdown current. Low Temperature Coefcient Key features include reversed-battery protection, Current and Thermal Limiting current limiting, overtemperature shutdown, Reversed-Battery Protection ultra-low-noise capability (SOIC-8 and DDPAK No-Load Stability versions), and is available in thermally efficient packaging. The MIC5209 is available in adjustable or 1% Output Accuracy fixed output voltages.
