The resistor values quoted in the instructions yeild an output voltage of around 13V when it should be 5V. The datasheet advises 13.3K Ohms for the lower resistor so I choose 12K. The equation the datasheet provides was used to calculate the value of the other resistor, aprox 39K Ohm to get 5V output, but this doesnt seem to work.
What values for R3 and R4 have you used to get 5V on the main board? Thanks.
