Hello,
I am having some trouble with a TPS780 adjustable regulator. I am trying to regulate 5V down to 1.5V, but my constructed circuit is regulating it to 2.220V instead. I calculated that I should use a 1M resistor for R2 and a 1.5K in series with a 232K for R1. The datasheet also says that Vfb should be 1.216V, but I am measuring it to be 1.770V.
