How to Use This Calculator
  1. Enter your supply voltage and the resistor values R1 (top) and R2 (bottom) in the divider network.
  2. Set the load resistance to model the circuit under load.
  3. Review unloaded and loaded output voltage, divider ratio, and quiescent current (mA).
  4. Check total current draw to ensure your power supply can handle the combined load.
