... Although the LT1027 does not have true force-sense capability, proper hook-up can improve line loss and ground loop problems significantly. Since the ground pin of the LT1027 carries only 2mA, it can be used as a low- pin is about 20k with side sense line, greatly reducing ground loop problems on the low side of the reference ...
