Circuit Arrangement For Voltage-Controlled Power Supply Of An Electrical Consumer In A Vehicle, And Use Of Such A Circuit Arrangement

A circuit arrangement for supplying power to an electrical consumer in a vehicle, the circuit arrangement comprising:

• a voltage regulator component comprising:
• an input terminal for inputting an input voltage,
• an output terminal for outputting an output voltage to the electrical consumer for supplying power to the electrical consumer, and
• a feedback terminal for inputting a feedback voltage that is dependent on the output voltage and that uses the voltage regulator component as a control variable for regulating the output voltage;
• an output line running from the output terminal to the electrical consumer;
• and
• a feedback circuit connected to a circuit node of the output line and to the feedback terminal for generating the feedback voltage from the output voltage tapped at the circuit node and for feeding the generated feedback voltage to the feedback terminal,
• wherein the circuit arrangement further comprises a semiconductor component arranged in a portion of the output line between the output terminal and the circuit node, the semiconductor component comes to have a high impedance in the event of an excessively high voltage arising in a portion of the output line between the semiconductor component and the electrical consumer in order to prevent an excessive voltage increase at the output terminal.
