General Description
The MIC5254 is an efficient, precise, dual CMOS voltage regulator. It offers better than 1% initial accuracy, extremely low dropout voltage (typically 135mV at 150mA) and low ground current (typically 90µA) over load. The MIC5254 features two independent LDOs with error flags that indicate an output fault condition such as overcurrent, thermal shut-down and dropout.
