Nice job DenniZ,
I also just placed a free sample order from TI for same 2 regulators. TI will mail via FedEx, will I need to pay for delivery?

Nope, Not a red cent!
Best of all, I have always received my package in2 days placing the order. I was shocked when they mailed one out the same day that I requested it at about 4 P.M.

***UPDATE***

Ok all,
here are the (2) different TI 5v regulators that I ordered,
UCC383TDKTTT5G3 on the left and UCC383T5 on the right.
I have included front, back, and side views with dimensions, all measurements are in inches.


Hi DenniZ,

I have received the 383T-5 but when I ran the wires (+in to pin1, +out pin2, -in\out pin3) regulator just heats up. What am I going wrong?

The middle pin is ground. solder your (-) wires to the center pin. You will need 2 negative wires. One running from the batt's and one from the casing of the connector. if that makes any sense =P

Sorry I haven't checked on this thread for a while, I've been on a mission to convert my local tobacco shop and get them to move away from selling cheapo e-cigs for 70 dollars a kit.

Anyway, I have just put away all my building materials, however just for you I'll pull everything back out and make an extensive photo tutorial of how everything fits together =OP

I'll be back in about an hour or so with the photos and tutorial, on second thought getting the photos sorted and hosted may take a bit longer, maybe 1.5 hours or so??? I'll be back as soon as I can.

***Please read the whole tutorial before beginning***
Also read up and watch a video of how to solder if you are new/less then proficient at soldering. Since this is a mock build, I am not trimming down my leads or isolating the heat-sink of the Regulator (the metal tab with the screw hole in it), you will want to do both of these things to prevent headaches later. trim down the metal pins to what you need, wrap them up individually and also heat-shrink or electrical tape the back and metallic sides of the regulator to prevent short circuits.
#1

Tools you'll need:
Wire cutters
Pliers/Multi-tool
Soldering Iron + Solder

Optional tool:
Helping Hands

Components:
Voltage regulator
Momentary switch (SPST) 3 amp 125v
Wire
Lithium Batteries ( I use only protected 14500)
Electrical Tape

Optional Components:
Light Emitting Diode (LED)
Printed Circuit Board (PCB)

Optional RECOMMENDED
Master ON/OFF switch
Heat-shrink Tubing

#2
OK... Lets get started. Place Heat-shrink tubing on each wire prior to making a solder connection, or Electrical tape them well.

#3
Pin polarity/function on the TI REGULATOR

#4
(+) Voltage in, left most on a right-side-up Regulator with pins facing you.

#5
(-) Ground, Middle Pin

#6
(+) Voltage out, Right-most pin with Regulator facing up, pins facing down.

#7
How it looks wired up without an LED, If you are using an led, there should be one more ground (middle pin) and one more voltage out, (right pin).

#8
If you are using a battery box with a master on/off switch, this is how it should be wired for the (+) voltage in. Note how the (+) Voltage in passes through the momentary switch before entering the regulator

#9
This is how the (-) ground would wire into the master on/off of the battery box. If you are using another enclosure but still want a master on/off to shut down the entire device, solder it between these two wires.

#10
One of the ground wires (-) from the middle pin needs to connect to the battery connector, Note how it is soldered to the OUTSIDE of the connector.

#11
This is a close-up of the (-) ground wire soldered in #10

#12
This is a the (+ )voltage out.
dsc0547f.jpg


#13
Close up of #12, note how it attaches to the center of the battery connector Make sure it DOESN'T touch the side or you will have a short circuit

#14
If you are not using an LED, skip to #17 to check your wiring before testing your new PV.
Optional LED polarity, I didn't cut the LED leads down for this instructional, but you will want to trim them down. Keep the long end slightly longer so you can tell which is which. The LED will only function if the polarity is correct. It is important to shrink wrap or electrical tape the leads to the LED, failure to do so will result in a short circuit if and when they do touch.

#15
Connect the additional wire you added to the (-) ground in step #7 to the SHORT (-) end of the LED
dsc0554o.jpg


#16
Connect the additional wire you added to the (+) Voltage out in step #7 to the long end of the LED.
dsc0555i.jpg


#17
This is how everything should connect together. Make sure you trace out each wire and make sure your optional Master On/off switch is in the on position before test firing your new PV.
CONGRATS AND ENJOY, -DEE

For sure Vadim,
Let all of us see your work and please place a link to it at the new thread.
How to make a 5V mod with a TI regulator
Note to all, this thread has become quite long and has fulfilled its original purpose for the moment. In the future I plan to experiment with adjustable voltage TI regulators and will link through this thread. Until then please feel free to continue posting here or in the new thread.

Dee,
I might save you some work. I just posted a adjustable one over here:

Hi Denizz, Sorry about being MIA, busy at work, busy with the family, things just got to hectic. But now in Nov. 2010 things should be a lot calmer so I'll be back at this forum. Thank you for easy examples to follow. Yes I will be building a few boxes for my 2 friends as upcoming X-Mas gifts and will take pictures to show here.

BigBlue30, I found your post and was impressed, ordered the Adjustable Chips, voltage regulator Pot, heat sink and put it all together. I just love it; I can finally adjust the voltage just a bit to complement different 510 cartos. Awesome vape with proper voltage.
