Circuit arrangement for voltage regulation having a voltage divider and a regulating circuit. The voltage divider is arranged between a first potential and a reference-ground potential and has a plurality of diodes connected in series, wherein an output voltage is tapped off at a terminal of one of the diodes. The regulating circuit, to which the output voltage and a reference voltage are applied, regulates the first potential based on a comparison of the output voltage with the reference voltage. The divider ratio of the voltage divider is altered by activating or deactivating one or more of the diodes, and is additionally altered by setting a magnitude of a voltage drop across at least one of the diodes.
