simple 5v help

[Tarnacc]

I would like to make a 5v with a regulator. I have a 5v 3amp regulator from madvapes with control pin and need a little direction. I have done quite a bit of searching and I am familiar with the wonderful instructions to be found on madvapes but any detailed instructions I have found include the use of that little circuit board which I do not have.

I am sure I have seen 5v mods here which do not use that board but I have been unsuccessful at finding any pictures or instructions I could imulate. Could someone who knows what I am looking for and where to find it point me in the right direction please? I am sure it is here, I just can't seem to find it.

Not sure if this is what you are looking for ?

The board isn`t necessary it just makes things a little easier.

Yes, that is just what I needed. What is a 10uf cap?

You can ignore that as it's the wrong value anyway. And do use a heat sink on that chip.

The diagram is unclear, use two 3.7V cells.

Isn't that little tab with a hole in it the heat sink?

That's where you would attach a heat sink, screwing it on tightly to make full contact with the bottom of the plate. Taking a cue from CPUs a little heat sink grease is also a good idea.

Ahhh I understand thank you. Any recomendations for heat sink? My guess is that someone has a simple and effective around the house solution.

Home made?

A piece of aluminum a little wider and maybe twice as long firmly bolted to the reg. You could also hacksaw a slot in it. Also give the reg some room to breathe.
