Talk:Linear regulator

Vendor Reference

I keep trying to add something but it keeps getting reverted. I would like to discuss this, because I do not believe it to be "spam" yet everyone who reverts it keeps marking it as such. I am opening this to the general community.

I firmly believe that mentioning the number 1 supplier worldwide with a link (I will be happy to provide a resource) is not spam. Voltage regulators are not merely theoretical objects, they exist and are sold on a daily basis. As such, a link to a suppliers webpage is relevant as a reference to what regulators are available at present. It also gives an idea of what parameters are important and what average parameter values might be (by looking at the datasheet). Spam is when a user tries to put something on a page as vandalism or advertisement. Wikipedia is an information source, and providing information about reality is not spam! I will not revert unless I get support, but I do believe that this is realistic.--Lagrangian 17:57, 8 October 2007 (UTC)

Also I agree with Lagrangian that a link to a supplier is a good thing.194.81.223.66 (talk) 10:57, 2 June 2008 (UTC)

I don't know who keeps on asking for references, but electronics isn't a field where you just go out and find journal articles on the subject. The WikiPolice have made this a much more unpleasant place. —Preceding unsigned comment added by 72.95.244.161 (talk) 00:56, 3 October 2008 (UTC)

Merge of linear regulator and voltage stabilizer

This page overlaps very substantially with "Voltage Stabilizer".194.81.223.66 (talk) 10:56, 2 June 2008 (UTC)

I agree. So I suggest merging voltage stabilizer into linear regulator. At least until the "linear regulator" article gets so big that it needs to be split up. --68.0.124.33 (talk) 02:17, 3 August 2008 (UTC)

No guys keep both articles separate. It is really convenient to keep it this way. —Preceding unsigned comment added by 129.82.229.205 (talk) 22:35, 10 September 2008 (UTC)

Voltage regulator and voltage stabiliser really arent the same thing. The latter includes various non-regulating stabilising devices and methods such as barretters, leakage resistors etc

Adjustable Regulator invention date?

The article cites 1977 as the "invention" of the adjustable linear regulator. I have a book here dated 1972 with a schematic calling for the "Motorola MC1460 IC voltage regulator". It's 9 pins and adjustable with separate pins for various remote sensing stuff. 5 years seems like quite a date difference, and this book didn't make any sort of claims that the part was "new". The part is now obsolete (and hard to find info about), so should the article read 1977 as the date the first adjustable regulator still in use today was invented?—Preceding unsigned comment added by 150.135.211.246 (talk) 03:52, 16 April 2010 (UTC)

I'd be most surprised if 1977 or 1972 were the invention of the adjustable regulator, given that adding adjustability to most fixed reg designs is trivial, and regs had been around for decades before then.

What is really being described is a product launch, not an invention. I'll edit accordingly. 82.31.207.100 (talk) 10:14, 7 June 2010 (UTC)

Just to clarify, Dobkin's patent for the linear adjustable regulator (US 3617859) dates back to 1971 and was filed in 1970. 86.14.89.253 (talk) 23:33, 10 June 2011 (UTC)

Voltage divider and clarity

Discussion of V regs as voltage dividers is technically correct, but to anyone not already fully upto speed with how they work its quite misleading or unclear. If I get time.... 82.31.207.100 (talk) 10:15, 7 June 2010 (UTC)

LDO claim

I removed

Because of this, National Semiconductor claims the title of "LDO inventor".

because it was

• offtopic in the section it was in
• at best dubious, since mechanical LDO regs existed decades earlier

Tone

The tone of the Adjustable regulator section doesn't seem up to snuff. It should probably be rewritten. 24.229.125.115 (talk) 12:45, 23 December 2011 (UTC)

Lead

Most of the lead expains what a switching regulator is, as opposed to explaining what the linear regulator is. I find that to be confusing. --Frederico1234 (talk) 07:36, 17 August 2012 (UTC)

Article revision and unclear sentence

I made several fixes to the article that I believe will provide the reader with a better flow. I felt some sections were somewhat inverted or they should have been on their own.

The article says "Most linear regulators will continue to provide some output voltage approximately the dropout voltage below the input voltage for inputs below the nominal output voltage until the input voltage drops significantly." The sentence is somewhat confusing. I would recommend to rewrite it (I can't because it's unclear what the message is).

Figure in "Variable regulators" section shows wrong pass device

The device shown is a PMOS with source on Vout, from the connections of the error amp it is clear that the device should be an NMOS.

For an NMOS, the arrow point OUT of the device. If the device was a PMOS, the source (marked by the arrow) would need to be on the high voltage side (Vin), and the error amp input terminal connections would need to be switches.

This picture is used in the LDO article also. Cannot edit the picture. — Preceding unsigned comment added by AnnoE-9 (talk • contribs) 22:54, 7 July 2016 (UTC)
