The invention relates to a circuit to generate an output characteristic, having a constant voltage control circuit which receives a voltage supply and generates a constant output voltage; a current reduction section, which receives a control voltage and, depending on this, generates a control current which produces a change in the output voltage; and a limiter section which receives a lower and an upper limit voltage and optionally blocks or activates the current reduction section. The invention also relates to a corresponding method to generate an output characteristic.
