PRODUCTION DATA
R1 and R2 can be calculated for any output voltage using the formula shown in Figure 7-6. Sample resistor values for common output voltages are illustrated in Figure 6-2.
For best accuracy, make the parallel combination of R1 and R2 approximately equal to 19kΩ. This 19kΩ, in addition to the internal 8kΩ resistor, presents the same impedance to the error amp as the 27kΩ band-gap reference output. This impedance helps compensate for leakages into the error amp terminals.
