.5 vdc to 3 vdc max 500ma power supply schematic/chip needed

hi anybody got info on a :

.5vdc to 3 vdc 400ma max power supply schematic/ ic ?

mark

**Nonsense. It is quite easy to build a power supply that can be varied down to zero Volts. It is not quite as simple as using a single chip regulator however.

Agree, I thought originally that he wanted to convert a 0.5v source voltage UP to 3v.

That would need a switchmode type device, and would be more difficult to design and build.

**It's difficult to understand the original poster's requirements, as he/she appears to be severely illiterate. You could be correct. Subsequent posts from the OP have done nothing to clarify. I would encourage the OP to find someone whose first language is English and ask them to translate the request from their native language.

hi, was point 5 vdc to 3 vdc , i dont a bit more reasearch and i actually need 2 vdc @ 250 - 350 ma., thansk, mark

whats so hard about understanding : " .5vdc to 3 vdc 400ma max power supply schematic/ ic ? "

cant you see the decimal point in front of the 5 ??...

now where did i say that " I thought originally that he wanted to convert a 0.5v source

i never even hinted or said i wanted to convert ...

hey trevor are you screwing phil ?

u need to go over your basic english reading skills,,

hey trevor , you got any wooden volume control knobs on your website , to give my amp that smooooth sound ???

Hi No-One,

Its all in the ambiguity of your intial statement... it can be read 2 ways...

I quote

It can mean 0.5VDC to 3VDC Variable or 0.5VDC input and 3VDC Output.

I must admit I thought the latter when I read it and wondered what the

0.5VDC source would have been.

Anyway I hope you have your answer now .

Regards,

Mick

Noone...

You really need to get a grip...

Your english is in need of a lesson..

No one (not even you NO-ONE).. Said .5v AND 3V.. If you had (or inferred) ....AND.... you would, presumably, get answers that provide a .5V output AND a 3V output...

.5v TO 3V can mean .5V in to 3V out. As in 240VAC to 12VDC

it can also mean

Variable between .5v and 3V. (with inference on The output voltage)

I find it hard to believe that you cannot bring yourself to see that glaring amiguity, but instead jump down peoples throats for asking for more information on your problem.

You seriously are not going about things the right way if you are in need of answers ... People (except those wanting to inflame) would just ignore you.

No... its more obvious there due to the huge step up range and the fact that `power supply' is mentoned AFTER the range ..... but the ambiguity still (technically) exists but because of the way it is said the automatic inferrence is a variable output...

The bottom line is If you want answers .. be nice... if you want to play games go about things the way you are..

Regards,

Mick

if i wanted a .5 and 3 i would have said .5 AND 3 .

but i said .5 to 3 v.

so when you see 1 vdc to 30 v power supply for sale , you automatically think its 1v and 30 ??

yeah okay

Hey Mick We can only hope the onrush of teenage hormones will abate a bit in a few years and then perhaps with some life experience under it's belt there may be some improvement in manners and knowledge.

Wadafuk u meen Trevy u dardy dood LOL!

Written job applications are a good thing - you can weed out a lot of crap very easily.

Actually no a lot of the time written skills bears little relevance to many positions apart from some box ticking on the computer Some the best sales people are near illiterate but can smooze terribly well
