摘要：
A circuit arrangement comprises a voltage regulator coupled to an external voltage supply and a control loop associated with the voltage regulator. The control loop includes an electrical current controller for setting the electrical current value, an analog-digital converter, a reference resistor and a computation/control unit coupled with the voltage regulator and the said analog-digital converter, and the control loop is so embodied that the voltage regulator, as a function of the presently set electrical current value, controls a voltage to an external load connected with the electrical current output. Particularly the computation/control unit is adapted to calculate a voltage to be delivered by the voltage regulator and to operate both, the electrical current controller and the voltage regulator for setting the electrical current value and to operate and for tuning the voltage delivered by the voltage regulator as a function of the presently set electrical current value, respectively.
