Abstract
A voltage regulator circuit arranged to receive a voltage supply signal, and to output a regulated voltage signal is described. The voltage regulator circuit comprises at least one switched mode power supply component selectively configurable to perform regulation of the voltage supply signal, at least one linear voltage regulator component selectively configurable to perform regulation of the voltage supply signal, and at least one controller component. The at least one controller component is arranged to receive an indication of a voltage level of the voltage supply signal, and configure a bulk connection for at least one switching device of the at least one linear voltage regulator component such that current flow from an output of the voltage regulator circuit to an input of the voltage regulator circuit through the bulk of the at least one switching device of the at least one linear voltage regulator component is resisted, if the indicated voltage level of the voltage supply signal is less than the threshold voltage level.
