The Texas Instruments LM2941QML-SP is a positive voltage regulator qualified for use in military, defence and space-based applications. 

The regulator is originally designed for vehicular applications and the circuitry are protected from two-battery jumps or reverse battery installations. The regulator will automatically shut down during line transients such as load dump, to protect both the load and the internal circuits. Features such as short circuit and thermal overload protection are also available for the regulator. 

The ground pin current due to the differential between the input and output voltage is reduced by a quiescent current reduction circuit. Higher quiescent currents only exist when the regulator is in the dropout mode.
