Description
General part information
MIC2951 Series
The MIC2950 and MIC2951 are "bulletproof" micropower voltage regulators with very low dropout voltage (typically 40mV at light loads and 250mV at 100mA) and very low quiescent currents. Like their predecessors, the LP2950 and LP2951, the quiescent current of the MIC2950/MIC2951 increases only slightly in dropout, thus prolonging battery life. The MIC2950/MIC2951 are pin-for-pin compatible with the LP2950/LP2951, but offer lower dropout, lower quiescent current, reverse battery protection, and automotive load dump protection.
The key additional features and protection offered include higher output current (150mA), positive transient protection for up to 60V (load dump), and the ability to survive an unregulated input voltage transient of -20V below ground (reverse battery).
The plastic DIP and SOIC versions offer additional system functions such as programmable output voltage and logic-controlled shutdown. The 3-pin TO-92 MIC2950 is pin-for-pin compatible with the older 5V regulators.
