A power supply circuit arrangement is provided that includes a switching regulator for generating a first regulated voltage, a controlled load element that is impinged upon by the first regulated voltage, and a first control element for controlling the load element. A method for generating a supply voltage is also provided. The switching regulator is adapted to generate a second, unregulated voltage that serves directly or indirectly as a supply voltage for the first control element. The circuit arrangement and method are used for example for a battery-based power supply of electric automotive components.
