my compact LM317

[billyblanko]

built this today with "not much space" being the issue ...thought i`d share a few pikz with ya ..

Not bad! What's the wattage on that pot though? And how much current do you plan on passing through the LM317?

 

[Cyparagon]

According to my math, the power dissipated by the pot reaches a maximum of 39mW when set at 10Ω. It falls on either side of that setting.

Even the smallest of pots are usually rated for 100mW.

Oh, I didn't bother reading the resistance code =p

+1 from me.

That's totally the style of driver I used to love putting together. Mucho respect for the creativity

I can already see it - you're going to have a lot of fun once someone convinces you to grab a copy of Eagle and start making PCBs

Now that's a nice small package . I'm going to try and do something like this for my next lm317.
