Caution
The S-816 Series has an internal impedance resulting from R
pin, as shown in Figure 13. Therefore, the influence of the internal resistances (R
be taken into consideration in defining the output voltage (OUT).
The output voltage (OUT) is expressed by the following equation:
In this case, V
the external resistances, and R
The accuracy of the output voltage (OUT) is determined by the absolute accuracy of external connecting
resistances R
the absolute value of the internal resistance (R
The maximum value (OUTmax) and the minimum value (OUTmin) of the output voltage (OUT), including
deviations, are expressed by the following equations:
Where R

If a value of R
median voltage deviation of the output voltage (OUT) will be obtained.
The closer the output voltage (OUT) and the output voltage set value (V
other, the more the accuracy of the output voltage (OUT) remains immune to deviations in the absolute
accuracy of external resistances (R
In particular, to suppress the influence of deviations in the internal resistance (R

tradeoff between the accuracy of the output voltage (OUT) and the reactive current. This should be taken
into consideration, according to the requirements of the intended application.
Note that when larger value (more than 1 MΩ) is taken for the external resistances (R
vulnerable to external noise. Check the influence of this value well with the actual application.
Furthermore, add a capacitor C
