1. An overvoltage protection circuit for a control unit for a vehicle, comprising:
an input terminal for applying an electrical input voltage, a test terminal for the application of an electrical test voltage, and an output terminal for providing an electrical output voltage to supply the control unit;
a reference device to provide a reference voltage using the input voltage;
a dividing device to provide a divided voltage using the output voltage;
a control device to provide a regulation signal using the reference voltage and the divided voltage;
a regulation device connected between the input terminal and the output terminal, wherein the regulation device is configured to provide the output voltage using the input voltage and the regulation signal;
a modification device to modify a value of the divided voltage using the test voltage; and
an adjusting device for adjusting the regulation signal using the input voltage, wherein the adjusting device includes a series circuit having a switch and a first electrical adjusting element, and wherein the switch is switchable depending on the input voltage.
