power regulator kit?

Justin_Case · 10th June 2006, 04:16 PM

I remember seeing a power regulator article years ago in The Audio Amateur about a op amp power regulator. I believe it was by Brian Seltzer. Are there any kits for something simular out there. I need to regulate 11 volts at about 3 watts.

Thanks,

Justin

Hi,
3W is only 300mA. You can easily achieve this with an LM317 chip regulator. Look up the datasheet for details.

I need 11 volts not 17 volts. I can't find an 11 volt three terminal power IC regulator. Besides, someone told me that they sound bad compared to a supply using an op amp. Surely someone makes a kit of something like the Seltzer regulator.........

I thought this a hard core audio fanatic forum. I did a search for Seltzer regulator but can't find anything about it.

Thanks,

Justin

Try looking for Sultzer regulator. There are no 11V fixed regulators.

Hi Justin,
I misunderstood your question.
I thought you wanted a regulated supply FOR an opamp.

BTW. LM317 is an adjustable voltage regulator. It can be set for 11V and upto 1.5A depending on dissipation/temperature.

Have a look at Perander's site. Search recent threads (todays) for relevant topics.

What is the URL for the PERANDER company? Do they have kits? I can't find this company on Googel.....

Justin,

I still have boards and parts for the Scalable PSU/regulator - see the thread in the group buys section. Although the thread is focused on 15V, you can make it 11V by swapping the voltage reference and one of the feedback resistors. In case you want something a little more interesting than an LM317.

The board is $5 and the parts kit $20.25

Hi, justin, your answers are available here (and elsewhere)... you probably won't get your regulater done this evening. The 317-337 system might work best if you're in a hurry. It can be adjusted to Exactly 11 volts(both + and -) if you check out the individual components datasheets. It's not expensive. I (personally) don't know of a kit for this but it might be out there. -

I am supposed to wade through 32 pages of post to see what you are talking about..... all I could find is a schematic of a discrete transistor design and no specifications as to performance.

Someone told me that Walt Jung designed a improved version of the Sulzer regulator and I guess I will have to do a web search to find that since it appears I am having little luck here. I am not interested in something as crude as a three terminal regulator (with a 20 something year old IC part number) or as complicated as discrete transistor design ( ithout good documentation that I can find easily.

Nobody here can actually help me find AN OP AMP BASED FAIRLY SIMPLE VOLTAGE REGULATOR WITH HIGH PERFORMANCE?

Hi,
look up Walt Jung. He has his own site updated with a series of older design articles for opamp regulators and super regulators. With this info you can go (informed) shopping.

Look up Peranders here, there is a web link on his data.
