Actually the pin out for both 78 and 79 devices is easy to remember. Very much the last choice you should make. Your might be “blown”.

I am assembling a metal detector kit of parts. If you have the space and have checked the pinout 79xx dtaasheet regulator pinout is not the same as 78xx positive regulator pinout then go ahead. AS I said it is a poor one to be used only in dire circumstances and only as a last choice.
What is the use of negative regulators? You’d need a negative supply to test it. It’s there to ensure that no more than 5 volts gets sunk into ground. And more comprehensible than dataheet You have to be careful, because most regulators are designed to only source current, they can’t sink much. Docedison on Jun 20, Sign up using Facebook. Read times previous topic – next topic. I am in Morocco and they aren’t that easy to find. So, try checking the wiring diagram in the data sheet and measure the output off load just to confirm it is producing -5V.
The voltage can be positive or negative or AC, which swings both positive and negative. You didn’t damage it as it is protected for reverse insertion internally.

Thanks for your replies! 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 7905vt voltage on a 79xx The can naturally replace the 79L If you wire up a negative voltage regulator backwards won’t it have to sink current?
Docedison Faraday Member Posts: Batteries could be smaller fewer cells and last longer. For example, many op-amp circuits require both a positive and negative supply.
Now with Unlimited Eagle board sizes! Some audio circuits use two 9V batteries Home Questions Tags Users Unanswered.
I was getting a test reading of Email Required, but never shown. I’ve done it once in 50 years and it was a bad move then, never again. If you are building a “bi-polar” power supply, you datashert use a to regulate the positive voltage, and a to regulate the negative voltage.

Post as a guest Name. Is there w way I can salvage my negative resistors to steadily output 5v? So I have concluded that I should replace the voltage regulator U1 79L That is the reason why I recommended the other part Th only other issue is that the ‘legs’ on the MCCT which is -5V 1A need to be gently filed to allow them through the holes in the board.
Have at it with that one.
However, just to be sure I have a good understanding of what it is for: I may not comprehend the idea of negative voltage. So what’s the difference between the 2? Discussion has been re-started by post 7. Under certain circumstances it Might work but there will always be those reversed polarity issued there. 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.
