Applications

* INFORMATION R1 and R2 must be placed only in ST779 applications to set the output voltage according to the following equation: VOUT = (1.23) [(R1+R2)/R2] and to simplify the resistor selection: R1 = R2 [(VOUT/1.23)-1] It is possible to use a wide range of values for R2 (10KΩ to 50KΩ) with no signifi
