About Voltage Divider Optimizer

Calculator of standard resistor values that minimize error in a voltage divider.

◘ Quickly find standard value resistors that minimize voltage divider error

◘ Handy tool for electrical engineers creating PCB-level designs

◘ Supports standard resistor values from 0.1% through 5% tolerance

◘ No annoying advertisements or in-app purchases

◘ Please submit your feedback & suggestions in the comments below

Many voltage regulators use a resistor voltage divider to set the output voltage. However, the selection of the optimal resistor values is complicated by the quantization imposed by standard resistor values. This app simplifies the process by calculating the standard resistor values that minimize error to the specified target output voltage. I created this app for my own use as an electrical engineer but decided to make it public on Google Play in case it might be useful to others.

What's new in the latest 1.03

Last updated on 2022-09-22

Version 1.03 - Adds a floating "back" button on the resistor list screen in order to make it easier to go back to the resistor divider page and make adjustments (on devices without an explicit back button it wasn't possible to go back due to the swipe gesture being used to scroll the resistor list horizontally). Thanks to Matt S. for the suggestion!
