Reference Designer Calculators
Resistor Calculator for Regulatorss r
The formula for the Output voltage is given by
Vout = Vref *( 1+ R1/R2)
R1 = (Vout/Vref -1)*R2
Where,
Vout Output Voltage
Vref Regulator Reference Voltage
R1 Feedback Resistor connected between output and feedback pin of IC
R2 Feedback resistor connected between Feedback pin and Ground
You can enter the values of the Reference Voltage, Output Voltage and R2 to Calculate the R1.
