Need Help with a DIY Project LD11117V33

[Robert_Fay]

Hello @ToneySalaz,

Just based off what you are saying it is working for a week and then the regulator is burning out, my first thought is heat. Are you using any heat sinking?

Take a look at this post from one of our engineers.

Cooling Requirements for Linear Voltage Regulator

Many electronic designs require more than one voltage rail for different portions of a system. For example, one might have a higher voltage motor which is controlled by lower voltage electronics. In such a system, it is most convenient to supply the overall system with the highest voltage required, and then step that voltage down to a lower voltage rail for the control electronics. The go-to device for many people designing such systems is a linear voltage regulator. Linear regulators are co…
