I was quoting the values directly from the users guide provided by FIRST. I agree the circuit past the regulator is run off 5 vdc, but the board it's self is powered by >7.2 vdc to 10 vdc. In the users guide it says that it "assumes" the board is powered by 12 vdc.
Either way, the load drawn by circuit when one LED is on should not exceed the ability of the regulator to power the circuit without failing.

If there is a problem with the circuit, FIRST will find it, maybe with the help of some of us, (Remember the Bane-Bot trannies from last year?) and suggest, provide or publish the solution.
