A voltage generator arrangement supplies a largely constant output voltage with
a high current driver capability. A bandgap reference circuit is downstream from
an impedance converter and downstream a voltage generator. The bandgap reference
circuit and the impedance converter on the one hand and the voltage generator on
the other hand are connected to different reference ground potential line. The
impedance converter contains a charge pump circuit to provide increased control
potential, which drives the voltage generator. The voltage generator in contrast
produces a reduced output potential. The influence of any voltage drop on that
reference ground potential line to which the voltage generator is connected in
the output potential is thus likewise reduced.
