Adjustable Voltage Regulator Resistor Divider Calculator

This calculator computes the resistor divider network for most adjustable voltage regulators whether they are linear or switching.

Voltage Regulator Circuit Schematic

Input:
Reference Voltage (Vr)
Output Voltage	(V)
R1	(KOhm)
Result:
R2	(KOhm)

See our standard resistor calculator for a real world resistor value.

Equations:

R2= (Vo-Vr)*R1/Vr
