ABSTRACT:
A voltage-regulating circuit comprises a series voltage stabilizer which includes a regulation element (Q.sub.1) arranged in series with an output for supplying an output voltage to a load (Z.sub.L). A comparison circuit (Q2-Q7) control the regulation element. The comparison circuit has a first input connected to a reference-voltage circuit (T3, D1) and a second input for receiving at least a part of the output voltage of the series stabilizer. A parallel stabilizer (D2) is arranged in parallel with the output of the series stabilizer. The parallel stabilizer is adapted to generate an output voltage equal to that of the series stabilizer.
