LM2940 Spice Model. 1A Low Dropout Regulator. Tthe LM2940C and all regulated circuitry are protected from re- verse battery installations or 2-battery jumps. During line transients, such as load dump when the input voltage can momentarily exceed the specified maximum operating volt- age, the regulator will automatically shut down to protect both the internal circuits and the load.
