> Only if you have no AC current into the chip through these pins, which > I suspect when the chip is operating you do have. The matter of AC impedance is valid, but it is a separate issue. The original question, as I read it, was about DC voltage drop and what DC voltage to set the regulator to, in order to get the right on-die DC voltage. That part of the problem is independent of the AC bondwire impedance.
