Product data sheet
In the event that no external resistors are used the output voltage will be determined only
by the internal feedback resistors. The output voltage will be as follows: V

The output voltage of regulator 7 can be adjusted between 2.4 V and 10 V using two
external resistors (R1 and R2); see
global calculations to determine the output voltage at a given value of R1 and R2:
To meet an overall accuracy of 5 % the external resistors should have a 1 % tolerance
and the total resistance of the external resistors should have a value maximum 2 k .
