Voltage regulator selection. Any ideas?

[Darth Magnus.]

Hi guys, just looking for appropriate voltage regulators for my custom saber project. I'm running a 14.4v 2A battery pack to get the power up to my LEDs but I still need to power my Arduino nano (9v input) and my sound card.
So I need voltage regulators. But which ones, I have a couple of different ones in mind but would like to know what others might use
Any suggestions welcomed.

Most people use the 78xx series without capacitors. For your needs you would want a 7809 for 9 volt. However as your needs seem more sensitive to dropout, I would recommend the Dimension Engineering line of switching adjustable regulators. It is more expensive than building your own, and you will need the save space for it within the hilt, but they have integrated capacitors and heat solution. They also provide affordable international shipping. I would provide a link but that is somewhat frown upon here. Pm me if you need it.

This is my new go to. You have to make a little pcb/heat sink and add caps but its a great regulator and super small in the smaller package.

Awesome guys, thanks a heap.

your NANO has a voltage regulator built in no?

Haha yeah the nano does. My initial post was incorrect, I was planing on using an Arduino mini for this project as I had one lying around. Its input is 9v
