This pin is the positive side of the reference that allows remote load sensing to achieve
excellent load regulation. A minimum of 10uF capacitor must be connected from this
pin to ground to insure stability.

voltage during the load transient response. This pin must always be higher than Vout
in order for the device to regulate.
