Abstract
A regulating system comprises an input terminal for applying an input voltage, and an output terminal for providing an output voltage. A semiconductor element is connected between the input terminal and the output terminal and is operable to regulate the output voltage. A regulating signal generation circuit generates the regulating signal and comprises 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 induces a first current dependent on one of the output signals in the first current mirror path. A second current through the second current mirror path is dependent on the first current. A splitter circuit conducts 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.
