Many variants datasheeet the 79L05 and need a minimum load, otherwise they produce a too high absolute value output voltage. So, try checking the wiring diagram in the data sheet and measure the output off load just to confirm it is producing -5V.

AS I said it is a poor one to be used only in dire circumstances and only as a last choice. If you are building a “bi-polar” power supply, you might use a to regulate the positive voltage, and a to datqsheet the negative voltage.

Docedison on Jun 20, So what’s the difference between the 2? Don’t use the wrong part! 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 am in Morocco and they aren’t that easy to find. You didn’t damage it as it is protected for reverse insertion internally. At the end of stage 1 which involves building is ‘a simple linear regulator that provides the -5V power supply’.

Have at it with that one. Actually the pin out 790ct both 78 and 79 devices is easy to remember.

Home Questions Tags Users Unanswered. Andy aka k 10 The voltage can be positive or negative or AC, which swings both positive and negative. Is it as simple as reversing the polarity?

Sign up using Facebook. I hope this is clear. Batteries could be smaller fewer cells and last longer. Docedison Faraday Member Posts: I’ve done it once in 50 years and it was a bad move datzsheet, never again.

I may not comprehend the idea of negative voltage. Some audio circuits use two 9V batteries It’s there to ensure that no more than 5 volts gets sunk into ground. Thanks for your replies! Email Required, but 7905dt shown. If you wire up a negative voltage regulator backwards won’t dxtasheet have to sink current?

That is the reason why I recommended the other part Discussion has been re-started by post 7. 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.

I was getting a test reading of Is there w way I can salvage my negative resistors to steadily output 5v? Sign up using Email and Password. You have to be careful, because most regulators are designed to datazheet source current, they can’t sink much.

For example, many op-amp circuits require both a positive and negative supply. Michael Karcher 1, 3 9.

The answer dagasheet difference between a negative and a positive voltage regulator You’d need a negative supply to test it.

And more comprehensible than post Very much the last choice you should make.

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. I am assembling a metal detector kit of parts.

difference between a negative and a positive voltage regulator?

Step one operates the 79L05 completely unloaded, which can cause Why xatasheet simply buy another U1 79L Your might be “blown”. Under certain circumstances it Might work but there will always be those reversed polarity issued there.

Get am LM it is a TO case regulator just like the but it will work down to a. Lol, thanks for your reply doc, I’ll take note of that.
