PRODUCTION DATA.
R5 and R6 set the output voltage level. The ratio of these resistors is calculated from Equation 13:
For a 5-V output, the R5/R6 ratio calculates to 3.082. Choose the resistors from standard value resistors. A good starting point is selection in the range of 1 kΩ to 10 kΩ. Values of 5.11 kΩ for R5,and 1.65 kΩ for R6, were selected.
