Will most electronic components work with 1 amp?

Im trying to find a 5V voltage regulator but all i can find are 1 amp.

So - what's wrong with that?

Yes, exactly, it's like saying, 'I'm trying to find red paint, but all I can find is 4 litre tins'. Nothing wrong with that, except it's a statement and not a question.

Jim, you really need to be a lot more specific about what your needs are.


Quick question? Are you using google? Because there are ALOT, SEVERAL, MANY options for voltage regulators which will work with ALL sorts of amperages. Hell, a quick search on ebay yields 2A 3A 5A buck converters. You clearly did not look hard enough before asking us to google it for you. Not only that but your question is annoyingly vague. It is equivalent to saying "I have a problem with my arduino, does this happen often and can you fix it for me?"

Ps991, you are making assumptions about what Jim needs. It appears you are assuming he is wanting to go up higher with current, but that might not be the case. He might also be after a specifc package, not a module. He might be after a unit with DC input, not AC input. He might be after a regulator that has low ripple, but he doesn't say, and you can't assume. And, he didn't ask anyone to google for him, or are my eyes so bad I can't read :P


In any case, even if the only supplies on the planet were 1A, the question makes no sense since you need to add up the current draws of all the components hooked up.

Even if "most electronic components work with 1 amp" if you had 3x components at .5A each, then no, that 1A supply is not enough.

Or, you could run 50 LEDs at 20mA each.....

Common knowledge dictates that you can use a 1a even if you needed lower amperage, so my guess is that u would need bigger. Buck converters are DC to DC. However if he needs ac there are several options as well all over eBay. Because he did not specify anything specific about specific requirements or sizes we have to assume by common sense he is just looking for a general large amperage regulator, otherwise a person with common sense would know that we cannot read minds and list those requirements.

That is why I gave the answer I did, harsh as it was.

Ps991, you're assuming everyone has

Common knowledge

How many times do we see on forums like this where people don't yet have a good understanding of 'current flow', thinking you push 'current' into a device or load? I see it a lot. :o

Because he did not specify anything specific about specific requirements or sizes we have to assume by common sense

I find it best never to make assumptions, unless I state it as an assumption to help the person asking. But to blindly assume, I have see it all too often ending up with everyone becoming confused, and so avoid doing so when I can.


Voltage regulator as on Linear regulator, take in 12V and output 5V?

Or 5V wallwart, such as http://www.dipmicro.com/store/DCA-0510 http://www.dipmicro.com/store/DCA-0520 http://www.mpja.com/5-Volt-DC-Plug-Power-Supply-4A-Regulated/productinfo/18520%20PS/

Or a board mountable switch regulator such as http://www.digikey.com/product-search/en?pv1525=62&FV=fff40042%2Cfff800df&k=oki+murata&mnonly=0&newproducts=0&ColumnSort=0&page=1&quantity=0&ptm=0&fid=0&pageSize=25

Or a stepup or stepdown regulator, see www.pololu.com

Fifteen words, essentially no information, eight “answers”, many quite verbose! :astonished:

Funny that, you would expect it to be the other way with verbose initial question with clear specifics and then clear short answers of around 15 words. :o

Not me, used to seeing all kinds of answers and off topic discussions for any topic post. Sometimes for days on end, with no follow up from the OP.
