Patent ID: 7012410

Claim:
A regulating system comprising: an input terminal operable to receive an input voltage; an output terminal operable to provide an output voltage and an output current; a semiconductor element operable to regulate the output voltage, the semiconductor element including a load path connected between the input terminal and the output terminal, and a control input to which a regulating signal is applied; a regulating signal generation circuit operable to generate the regulating signal, the regulating signal generation circuit having a current mirror arrangement including a first and second current mirror path, wherein a controlled current source is connected in series to the first current mirror path, the controlled current source operable to induce a first current dependent on one of the output voltage and output current in the first current mirror path, and wherein a second current through the second current mirror path is dependent on the first current; and a splitter circuit operable to conduct the second current to the output terminal or to a reference potential, dependent on a load path voltage applied over the load path of the semiconductor element.
