Please help with wiring diagram please !!

Ok i need someone to please help me and show me how to install this regulator to make my mod 5v . I would appreciate a diagram I do best with an actual diagram its easier for me to follow here is my existing wiring and the regulator i want to use thank you so much for your help

Here are some old diagrams I have. Not sure if it's relevant to your regulator.

Ok i need someone to please help me and show me how to install this regulator to make my mod 5v

need a bit more info please... and if its at madvapes there should be a spec sheet explain the pins...

edit- i dont see a control pin... make sure to use a 3a switch...

this regulator has to pins (one Vin and one Vout) and a plate on the back that is the ground...
i believe this would work...
(made a small changes to the last diagram)
pretty sure it would work... but i has never used one of these...
can someone back this up or say im wrong?

I can't show you, but disconnect the LED from the switch, connect out of switch to p1 (left as shown) on regulator connect p3 (right as shown) to atty also p3 to 470Ω resistor and led, add 10uF capacitor between p1 and ground(p2) as well as 10uF capacitor between p3 and ground (p2) connect p2 to battery neg(-) and it should work.

ah! so like this? right?

but i seen many mods without the caps...

what is sw1 i have only 1 switch which is the master on and off switch

 

[outofjuice]

its the fire switch... for when you take a hit, like all manual batts mods (most of them are...) use a good 3amp switch for it like this
Horn style switch -- Black
edit- wait... so you mean your going without the master switch and just going with a fire switch? it works all the same

Looks good to me, the caps help to prevent power leaking when off, with the LED after the switch they aren't as necessary, but I still like using them. It also helps to prevent the LED from working as a solar cell.

hmmm... i always thought a master switch takes care of that problem... added the led just in case you know lol

yes thats what i meant no master switch its just a plain tube mod the one from madvapes i just wanted a regulator to make it 5v instead of 6v

 

[outofjuice]

without the master switch you should be fine... (and if the drain is something your worried about add the caps)
hmmm be sure to post some pics

 

[Brooklynguy1]

yep no master switch its just the goldrush tube mod from madvaped i just wanted a regulator for 5v instead of 6 ................ So the capacitor ends go to the ground tab on the regulator rite then wired as shown rite i just wanna make sure

thank you both for your help i appreciate it so much

good stuff man, let let us know how it goes

I've also used a NCP5667, although while testing it on the breadboard (in accordance to this diagram), the solder joint on the ground back plate came loose but continued to work. Is this safe?

Can't you just resolder it? The regulator can't work without the ground connection (battery minus). It might pass current with a floating ground, but it definitely would not be regulated properly.
