I only realized I bought the wrong thing because when I hooked it up to power my breadboard, I was getting 4 volts when I was expecting 5 for my attiny.

So what’s the difference between the 2? What is the use of negative regulators? Don’t use the wrong part!

A voltage or voltage measurement is referenced to something, usually to ground. The voltage can be positive or negative or AC, which swings both positive and negative. For example, many op-amp circuits require both a positive and negative supply.

If you are building a “bi-polar” power supply, you might use a to regulate the positive voltage, and a to regulate the negative voltage. In some cases, such as with a battery, you can simply reverse the connections to get a negative voltage. Some audio circuits use two 9V batteries Your might be “blown”. You’d need a negative supply to test it.

Or you could use a 9V battery, or a power supply with an isolated ground connected “backwards”.

Docedison Faraday Member Posts: You didn’t damage it as it is protected for reverse insertion internally. Get am LM it is a TO case regulator just like the but it will work down to a. Xatasheet LM or any ‘ requires 2. Batteries could be smaller fewer cells and last longer. Thanks for your replies! Is there w way I can salvage my negative resistors to steadily output 5v? Is it as simple as reversing the polarity? Under certain circumstances it Might work but there will always be those datashset polarity issued there.

That is the reason why I recommended the other part Very much the last choice you should make. AS I said it is a poor one to be used only datashfet dire circumstances and only as a last choice.

I’ve done it once in 50 years and it was a bad move then, never again. Lol, thanks for your reply doc, I’ll take note of that. However, just to be sure I have datassheet good understanding of what it is for: It’s there to ensure that no more than 5 volts gets sunk into ground.

I may not comprehend the idea of negative voltage. Docedison on Jun 20, Now with Unlimited Eagle board sizes!

Discussion has been re-started by post 7. Have at it with that one. CrossRoads on Apr 24, And more comprehensible than post And more fun than post 7;- first OP case is fine. The answer for difference between a negative and a positive voltage regulator You have to be careful, because most regulators are designed to only source current, they can’t sink much.

If you wire up a negative voltage regulator backwards won’t it have to sink current?
