You didn’t damage it as it is protected for reverse insertion internally. Your might be “blown”. For example, many op-amp circuits require both a positive and negative supply. Under certain circumstances it Might work but there will always be those reversed polarity issued there.

So what’s the difference between the 2? CrossRoads on Apr 24, By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.

If you wire up a negative voltage regulator backwards won’t it have to sink current? The answer for difference between a negative and a positive voltage regulator Home Questions Tags Users Unanswered. If with a 1mA load 5k resistor the voltage drops to -5V, your chip is OK. Pin 1 is most positive voltage 0V on a 79xx and input voltage on a 78xx Pin 2 is most negative voltage 0V on a 78xx and input voltage on a 79xx.


So I have concluded that I should replace the voltage regulator U1 79L Email Required, but never shown. Very much the last choice you should make. Get am LM it is a TO case datashheet just like the but it will work down to a.

And more fun than post 7;- first OP case is fine. Andy aka k 10 By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. Why not 79005ct buy another U1 79L So, try checking the wiring diagram in the data sheet and measure the output off load just to confirm it is producing -5V.

Thanks for your replies! Is there w way Datasheer can salvage my negative resistors to steadily output 5v?

I was getting a test reading of Post as a guest Name. However, just to be sure I have a good understanding of what it is for: I only realized I bought the wrong datashdet because when I hooked it up to power my breadboard, I was getting 4 volts when I was expecting 5 for my attiny.


I’ve done it once in 50 years and it was a bad move then, never again. A voltage or voltage measurement is referenced to something, usually to ground.

And more comprehensible than post Sign up or log in Sign up using Google. Docedison Faraday Member Posts: Discussion has been re-started by post 7. It’s there to ensure that no more than 5 volts gets sunk into ground.

If you have the space and have checked the pinout 79xx negative regulator pinout is not the same as 78xx positive regulator pinout then go ahead. I may not comprehend the idea of negative voltage.

Lol, thanks for your reply doc, I’ll take note of that. Is it as simple as reversing the polarity? That is the reason why I recommended the other part Read times previous topic – next topic.
