An overvoltage protection circuit for a control unit for a vehicle includes an input terminal for applying an electrical input voltage, a test terminal for applying an electrical test voltage, and an output terminal for providing an electrical output voltage to supply the control unit. The overvoltage protection circuit also includes a reference device to provide a reference voltage using the input voltage. The overvoltage protection circuit includes a dividing device to provide a divided voltage using the output voltage. The overvoltage protection circuit includes a control device to provide a regulation signal using the reference and divided voltages. The overvoltage protection circuit includes a regulation device connected between the input and output terminals. The regulation device provides the output voltage using the input voltage and the regulation signal. The overvoltage protection circuit includes a modification device to modify a value of the divided voltage using the test voltage.
