D24VxFx 3.3V to 5V

Hello guys, I purchased several step down regulators but forgot to order a “5V Version”. I have 4x 3.3V and 2x 9V Regulators - is there a way to change the output voltage to 5V? I think I just have to change two resistors - right?! Of course I could purchase the 5V Version but shipping ist not that cheap. So it would be amazing if you could help me :slight_smile:

Here is a picture:

Maybe someone could tell me the values for resistor 1 and resistor 2.
Thank you :slight_smile:


The “D24VxFx” name you mention applies to a few different regulator families that we have. From the pictures, it looks like you are referring to the D24V6Fx or D24V3Fx regulators. For those regulators, you can change the output voltage by replacing the two resistors you labeled. To get 5V out of that regulator, the ratio between resistor 2 and 1 should be about 5.61:1. Since resistor 1 is 2.05kΩ on both the 3.3V and 9V version of the regulator, you could try replacing resistor 2 with a 11.5kΩ resistor to get 5V from the output.

Thank you I just tried it - it works perfect :slight_smile:
