bought a +5VDC voltage regulator from Radioshack.. says up to 1 amp output current.. can i use this for a 5v nicostick?
5VDC Regulator.. 1 Amp Can i use???

It'll work. Not as hard as the full 2A, but it'll do the job. Remember the batteries are putting out less than 1.5A.
You can actually get 1A 5v regs at radioshack. adjustable LM317 ones too, if you know how to build the circuit. Here's a tip: running two regulators in parallel will give you the same voltage, but the current adds up. So two 1A regs in parallel gives you 2A. So two of the ones at radioshack will do ya. Two of the 1.5A will give you 3A. I dunno what that'll do...

Oh, lol, I only saw your most recent post lol. The two radioshack regulators in parallel will give you two amps at 5 volts.
so if i use just one... will it still work until i can get a better one?
That's incorrect.
To get 2 regs running in parallel is not an easy task, it requires additional circuitry. You'll need a means of forcing current sharing.
To the OP do yourself a favor and get a proper 3A reg.
WillyB, do you mean some caps and resistors?
About the batteries. How much current are they putting out? I thought (I'm new) they could do 800ma

oh. Well then nevermind what I said. I don't see what's so hard about two regs in parallel, tho.
Unless they are identical (which they aren't) it ain't gonna work without additional circuitry.Me neither
Assuming one outputs 4.9V and the other 5.1V the one with the lowest voltage will assume the whole burden till it overheats and it's internal thermal protection triggers, then the other will take over and the same thing will happen.
You would need to add some ballast/equalizing resistors in series with the regulator outputs. Doing so should make the regulators share current equally.
Seeing as regs that can handle 3A can be had for as low as a couple dollars it's hardly worth the time, expense, and space.
Hey guys.. i just got back from the ratshack, and all they have are 1 amp regs in 5v.. so i have one more electronics store to check on my way to work tomorrow.. hoping to find a 3a with a control pin.. keeping my fingers crossed!
I've messed with tons of these 5v regulators. I have one in my guitar amp running off of 18vDC at 5.6A to power my digital reverb. It doesn't get hot at all. Didn't even slap a heatsink on it.
I have to admit tho, I still don't know how MuddyBears plans on using it. With a transformer??

no i plan on making a 5v mod on perf board with a 10uf cap and 470 ohm resistor if i can find one with a control pin.. madvapes is out of stock at the moment..
Well what I mean was how are you supplying power to the 5v regulator(s)??
If you are using batteries there is absolutely no risk in putting two regs in parallel. Especially with a switch. About those regs from radioshack, i've never measured on that didn't read 5v exactly. I guess WillyB was talking about millivolts or something, however big the differences are I can't measure them. With such low voltages and current I don't see the things failing.

yes im using 2 14500's in parallel. im just not exactly sure how to bridge them together.. like i said i am relatively new to this electronics stuff and am learning as i go..
Hey Muddy, i don't know a heck of a lot and may have missed something. How are you going to get 5v? if you run 2- 3.7v Parallel?
