At the moment, I am using one of these to step my voltage down. It had been modified to use a resistor rather than the potentiometer so I can get a constant output.
They came in a pack of 2. One was my test board and is now broken. The one I am using now has just stopped working. I also don't want to use them because they have been designed to pull up to the maximum output voltage rather than dropping to 0 if the pot broke. This is a big issue if you have something sensitive like a micro controller on the output, which I did and it released its magic smoke.
I have some LED strips which are 24V. On them they just use a voltage divider to get a 5V output.
What are the downsides to using a voltage divider to take 24V down to 5V? Obviously things like over-current protection, reverse polarity protection would be on a prebuilt module but since I'm putting the voltage divider straight on the board that's not a worry.
