MIC5219YMT TR

MICREL SEMICONDUCTOR  MIC5219YMT TR  电压稳压器, LDO, 可调, 2.5V至12V输入, 350mV压差, 0.5A输出, µDFN-6

The is an efficient Linear Voltage Regulator with high peak output current capability, very-low-dropout voltage and better than 1% output voltage accuracy. Dropout is typically 10mV at light loads and less than 500mV at full load. The MIC5219 is designed to provide a peak output current for start-up conditions where higher inrush current is demanded. It features a 500mA peak output rating. Continuous output current is limited only by layout. The MIC5219 can be enabled or shut down by a CMOS or TTL compatible signal. When disabled, power consumption drops nearly to zero. Dropout ground current is minimized to help prolong battery life. Other key features include reversed-battery protection, current limiting, overtemperature shutdown and low noise performance with an ultra-low-noise option.
