Micrel, Inc. MIC5219 MIC5219 500mA-Peak Output LDO Regulator General Description Features The MIC5219 is an efficient linear voltage regulator with high 500mA output current capability peak output current capability, very-low-dropout voltage, and SOT-23-5 package - 500mA peak better than 1% output voltage accuracy. Dropout is typically 2mm2mm MLF package - 500mA continuous 10mV at light loads and less than 500mV at full load. 2mm2mm Thin MLF package - 500mA continuous The MIC5219 is designed to provide a peak output current for MSOP-8 package - 500mA continuous start-up conditions where higher inrush current is demanded. Low 500mV maximum dropout voltage at full load It features a 500mA peak output rating. Continuous output Extremely tight load and line regulation current is limited only by package and layout. Tiny SOT-23-5 and MM8 power MSOP-8 package The MIC5219 can be enabled or shut down by a CMOS or Ultra-low-noise output TTL compatible signal. When disabled, power consumption Low temperature coefficient drops nearly to zero. Dropout ground current is minimized to Current and thermal limiting help prolong battery life. Other key features include reversed- Reversed-battery protection battery protection, current limiting, overtemperature shutdown, CMOS/TTL-compatible enable/shutdown control and low noise performance with an ultra-low-noise option. Near-zero shutdown current The MIC5219 is available in adjustable or fixed output volt- Applications ages in the space-saving 6-pin (2mm 2mm) MLF , 6-pin (2mm 2mm) Thin MLF SOT-23-5 and MM8 8-pin power Laptop, notebook, and palmtop computers MSOP packages.
