摘要： Activatable/deactivatable circuit arrangement for producing an output reference voltage having a first transistor (T1) whose emitter is connected with a reference potential (M) and whose base and collector are connected with one another, having a second transistor (T2) whose base is connected with the base of the first transistor (T1), having a first resistor (R1) that is connected between the collector of the first transistor (T1) and an output terminal (U) for supplying the output reference voltage, having a second resistor (R2) that is connected between the collector of the second transistor (T2) and the output terminal (U), having a third resistor (R3) that is connected between the emitter of the second transistor (T2) and the reference potential (M), having a third transistor (T3) whose base is connected with the collector of the second transistor (T2) and whose emitter is connected with the reference potential (M), and having a controlled current source (T4) that is connected between a supply potential (V) and the output terminal (U), and that is coupled at the input side with the collector of the third transistor (T3), whereby the collector-emitter path of a fifth transistor (T5) is connected in parallel with the collector-emitter path of the third transistor (T3), and the base of the fifth transistor (T5) being driven by a switching signal (S).
