The invention relates to a method of regulating the power supply to at least one power consumer which is connected via a voltage regulator ( 2 ) to a voltage output of a DC voltage source ( 1 ) at which a supply voltage (U<SUB>0</SUB>) is present. To minimize power losses, it is proposed that (a) a regulation signal is generated for the voltage regulator ( 2 ) which regulation signal depends on at least one input voltage (U<SUB>in</SUB>) present at the voltage regulator ( 2 ) and on a reference value (V<SUB>ref</SUB>) which is specific of the voltage regulator ( 2 ), and (b) the supply voltage (U<SUB>0</SUB>) of the DC voltage source ( 1 ) is regulated in dependence on the regulation signal.
