The LT1086 is an adjustable voltage regulator. The voltage you get out is set by the ratio of two resistors connected to the regulator. Long wires might affect that ratio, but it shouldn't be a problem as long as the wire gauge is relatively substantial. The LT1086 was also used on the first generation PPC machines (NuBus PPC) to provide steady voltage to the PP601.
