Abstract

A protective circuit includes an input that provides a first supply voltage, a voltage regulator that provides a second supply voltage based on the first supply voltage, a measuring device that identifies an impedance of the voltage regulator, and a self-locking switching element configured to connect the first supply voltage with the voltage regulator if an impedance of the voltage regulator exceeds a predefined impedance value.
