... Like their predecessors, the LP2950 and LP2951, the quiescent current of the MIC2950/MIC2951 increases only slightly in dropout, thus pro-longing battery life. The MIC2950/MIC2951 are pin for pin compatible with the LP2950/LP2951, but offer lower dropout, lower quiescent current, reverse battery, and automotive load dump protection ...

... MIC2951 version with external resistors, a minimum load of 1µA is recomm-ended. A 0.1µF capacitor should be placed from the MIC2950/ MIC2951 input to ground if there is more than 10 inches of wire between the input and the AC filter capacitor battery is used as the input. Stray capacitance to the MIC2951 Feedback terminal (pin 7) can cause instability ...
