1. An apparatus comprising:

  • a switching voltage regulator coupled between a power supply node and power return node, capable of repeatedly opening and closing (1) a first low impedance path between an output node and the power supply node and (2) a second low impedance path between the output node and the power return node, to regulate a voltage of the output node;

    an integrated circuit (IC) having a supply voltage input coupled to the output node; and

    means for closing the second path but not the first path under control of a first signal that indicates a work capability mode of the integrated circuit.
