ABSTRACT:
A current source contains a first switching element which is provided with a control input and is embodied and arranged in such a way that an output flow on an output side of a current source can be adjusted according to a control signal at the control input. The current source also contains a reference resistance that is electrically coupled to a first switching element in such a way that a potential difference above the reference resistance represents the output flow. The adjustment signal of a regulator unit depends on the voltage difference above the reference resistance, is the control signal of the first switching element, and contains a time function element which limits a first value of the output flow to a maximum duration and then reduces the value of the output flow.
