Abstract: In a series voltage regulator having a regulating transistor (T) arranged with its emitter-to-collector path in a series arm of the regulator, the base of this regulating transistor being controlled by a differential amplifier (V) which compares a voltage proportional to the regulator output voltage (U.sub.2) with a reference voltage (U.sub.C), this reference voltage is available from a capacitor (C) to which a voltage limiting circuit (B) limiting the reference voltage to a maximum level (U.sub.R) is assigned, and which is connected to the output of a transconductance circuit (G) whose output current (I.sub.A) depends on the difference (U.sub.D) between the output voltage (U.sub.2) and the input voltage (U.sub.1) of the series voltage regulator.
