Hi All
I'm looking for info and guidance for a voltage regulator circuit I require.Basically as you can see from the title I'm looking at using a LM317 (because I have them) but I'm wanting to add a number of LED's to indicate when an adjusted voltage level is reached.
I've looked at using zener diodes but after testing I've not yet achieved what I require.
I have 24v 800ma input on the LM317 and I'm hoping to indicate the Vout via the led's from around 3v and then in multiples of 3v using 8 LED's in total, 3v output first LED lights up, 24v all eight light up (or something along those lines)
There maybe simpler methods or IC's but I'm unsure of the best practical way to do this.I would like to use my LM317 as I have them.
Many thanks
