PCI bus. And the USB host function is neither used at the moment nor necessary for the
remote control function. The third row in table 9.5 depicts the power consumption of the
CHARM after reducing the input voltage of the CHARM. Therefore, the input voltage is
adjusted to get the minimal dropout voltage

of the power regulator of the CHARM. This
gives an estimation of how much power can be saved removing the 5V power source and
removing the related power regulator.

The dropout voltage of a power regulator determines the lowest usable supply voltage.
