Voltage has a large effect on both static and dynamic power. Active control of the voltage level ensures the desired voltage is applied to the device.

  • Use switching regulators.

    Switching regulators are more power efficient than linear regulators, at the expense of requiring a higher component count.

  • Use adjustable regulators.

    Ensure voltage is as close as possible to the device and to the highest consuming device if the same supply powers multiple devices.

  • Select regulators with tight tolerances.
