... The MIC5246 offers better than 1% initial accuracy, extremely-low-dropout volt- age (typically 150mV at 150mA) and constant ground current (typically 85 A)over load . The MIC5246 features an error flag that indicates an output fault condition such as overcurrent, thermal shutdown and dropout. The MIC5246 provides a very low noise output, ideal for RF applications where quiet voltage sources are required ...
