ABSTRACT:
A regulator includes a first controllable semiconductor component, which has an input terminal connected to a regulator input, an output terminal connected to a regulator output, and a control terminal. A second semiconductor component is provided, which is connected to the control terminal of the first semiconductor component and has an input terminal, an output terminal and a control terminal. A comparison device that has a first input, a second input and an output connected to the control terminal of the second semiconductor component is further provided. A reference voltage can be applied to the first input of the comparison device and the second input is connected to the regulator output. A driver device, which, when a predetermined threshold value is exceeded by an input signal present at the regulator input, diverts part of the current from the control terminal of the first semiconductor component to the regulator output.
