Using a 5 volt regulator

Hey, I need to supply 5 volt's (approximately 2 amps) to an addressable RGB LED strip for a project.

I will need to power it from a LiPo pack that is at 7.2 - 8.4 volts. This is the regulator I have found 5pcs 78T05ACT 3 amp 5 volt positive voltage regulator for sale | eBay .

It says on the data sheet that it does not need any external components, but within the data sheet it says I might need a 0.33 micro farad capacitor between the input and ground leads. Only problem is, I don't know if I need it or not. Also if I do need it, will this work? 10uf 35V DN Series NEC Tantalum Radial Dipped Capacitor DN1V100M8S (Lot of 5) | eBay

I assume the positive lead on the capacitor needs to be on the input, but I just want to make sure, I don't want an explosion!

Thanks

You will need a heat sink for the regulator.

It never hurts to add the recommended capacitors to the input (and output) of a regulator.

You have linked to a 1uF cap. So unless you are going to put those three in series, it isn't 0.33uF. You can easily for 0.33uF (ceramic) caps on eBay.

You have stated in your post (or your profile) where you are in the world. They may be better options for fewer parts than eBay.

For more efficient use of your batterys, you may want to look at getting a UBEC from a hobby supplier like below. More efficient than the regulator chips.

Wow, Thanks I didn't even realize, I looked at my motor controller and it said it has a 5v 2A UBEC built in. I have an extra 2 so I can just pull from my spare parts bin.

I have always powered the receiver from the Arduino's 5 volt power supply and never noticed the motor controllers have their own.

Is the BEC a switch mode power supply?

I think a UBEC (which may be different than a BEC) is an efficient switched power supply. You can also find the UBECs on ebay for $4-5 including shipping, which would probably less total cost than the 3a regulator chip.
