Reducing cross-regulation interferences between voltage regulators

A device comprising:

• a first voltage regulator means for supplying an output voltage to a plurality of second voltage regulator means respectively connected to one or more loads of a plurality of loads;
• means for dynamically modulating the output voltage of the first voltage regulating means by varying the output voltage to adjust an amount of dropout voltage of one or more of the plurality of second voltage regulator means by adjusting the output voltage of the first voltage regulator means in response to an anticipated load change known at the first voltage regulator means but occurring to at least one of the plurality of second voltage regulator means;
• wherein the modulation of the output voltage by the first voltage regulator means is performed based on and prior to the load change.
