Abstract

A circuit arrangement for voltage regulation having a series regulator with a regulating amplifier and a charge pump that is connected downstream of the regulating amplifier, a reference voltage unit that generates a reference voltage for the regulating amplifier, and a starter unit that generates a starter voltage in order to supply the regulating amplifier, the charge pump, and the reference voltage unit with voltage while the series regulator is being started.
