Talk:Voltage regulator

message: 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 17:53, 8 October 2007 (UTC)

message: sir,
i want to design a voltage-regulator of 54VDC and max load current of upto 5Amp.The max input voltage is 60VDC and the range of
voltage at the output of regulator must be within 48-54Vdc.suggest
ckt.
thank you
What is the min input voltage?
If you want a linear regulator circuit, perhaps something like http://sound.whsites.net/project96.htm would be adequate, with paralleled output transistors (you'll need a big heat sink on the output transistors).
If you want a switching regulator, I see the LM5005 "integrated switcher" can handle the voltage, but only half your desired current -- perhaps use 2 of them.
Or you could use a "switching controller" such as the Roman Black voltage regulator with an external high-power transistor. Digikey lists dozens of FETs that appear to be more than adequate for around $2, such as the 500 V 12A Toshiba 2SK3568(Q).

message: As far as I can see from a quick search on the Internet, the terms VRM and Voltage regulator module seem to always refer to components specific to use in personal computers . The electronic component or circuit in general is called voltage regulator (without module). Two separate articles can be justified in this case. Paolo Liberatore (Talk) 14:22, 5 November 2005 (UTC)

message: The "voltage regulator" article needs to mention charge pump regulators.
Do integrated charge pump regulators exist?
If you are looking for voltage regulators that do not require an external inductor,
then yes, many "single-chip" charge pump voltage regulators exist.
They don't have any inductors, internal or external.
They do require a few more external capacitors than other kinds of voltage regulators.

replies: text: There are even a few charge pumps (such as the MAX233 and the MAX246) that don't require any external capacitors (only one cap across power and GND). Do they use on-chip capacitors (vaguely similar to DRAM), or do they use small discrete capacitors inside the package (more like a Multi-Chip Module and analogous to what the LM2825 apparently does) ?

replies: text:  I don't know about the MAX233 etc specifically, but there certainly are components that generate their own internal higher voltages via charge pumps that integrate all the capacitors on the silicon.  I don't know of any charge pump devices designed to power external devices that don't require external capacitors (though that hardly means they don't exist...). Evand 02:08, 29 May 2007 (UTC)

message: The arrows representing voltages in the diagrams in the sections Voltage regulator#Transistor regulator and Voltage regulator#Regulator with an operational amplifier seem to be reversed. I think that the arrow-head should point towards the positive terminal of the voltage represented. I would like to reverse the directions of the blue arrows in both of the diagrams. The images are SVG so this shouldn't be too difficult to do. This isn't some new convention for representing voltages with which I am unfamiliar, is it? --Nigelj (talk) 22:20, 17 November 2013 (UTC)

message: Dropout voltage does not appear to be a significant enough topic for a stand-alone article. I propose using the material in Dropout voltage to improve the Voltage regulator#Dropout voltage paragraph in this article and then redirect Dropout voltage to Voltage regulator#Dropout voltage. ~Kvng (talk) 15:39, 21 February 2017 (UTC)
replies: text: There was nothing referenced here anyway and the paragraph at Voltage regulator gives the definition well enough, so I've changed this to a redirect.--Wtshymanski (talk) 00:32, 2 August 2017 (UTC)

message: I came here to found out what is meant by a 1-, 2- and 6-phase voltage regulator. The article mentions "single--phase" and has a picture of a "3-phase" voltage regulator but does not describe what is meant by the term "phase". If someone knowledgeable could add information about what exactly is meant by "phase" and what the difference is between single and multi-phase voltage regulators, that would be great! 134.191.220.73 (talk) 08:06, 24 May 2019 (UTC)
