Microchip Technology, Inc. 500mA 1% Accuracy Low Noise LDO MIC5209

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 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 MIC5209 is available in adjustable or fixed output voltages. Additional Features Output voltage range: 1.8V to 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 SOIC-8 and DDPAK Ultra-small 3mm x 3mm DFN package
