The voltage can be positive or negative or AC, which swings both positive and negative. Michael Karcher 1, 3 9. Under certain circumstances it Might work but there will always be those reversed polarity issued there.

Andy aka k 10 So what’s the difference between the 2? I am in Morocco and they aren’t that easy to find.

Email Required, but never shown. Get am LM it is a TO case regulator just like the but it will work down to a. Actually the pin out for both 78 and 79 devices is easy to remember.
Discussion has been re-started by post 7. Why not simply buy another U1 79L Step one operates the 79L05 completely unloaded, which can cause You have to be careful, because most regulators are designed to only source current, they can’t sink much.
AS I said it is a poor one to be used only in dire circumstances and only as a last choice. Many variants of the 79L05 and need a minimum load, otherwise they produce a too high absolute value output voltage. For example, many op-amp circuits require both a positive datashwet negative supply.

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.
And more comprehensible than post I am assembling a metal detector kit of parts. Docedison Faraday Member Posts: And more fun than post 7;- first OP case is fine.
Some audio circuits use two 9V batteries Home Questions Tags Users Unanswered. Sign up or log in Sign up using Google. What is the use of negative regulators? 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. 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 The can naturally replace the 79L So I have concluded that I should replace the voltage regulator U1 79L CrossRoads on Apr 24, Batteries could be smaller fewer cells and last longer.
The LM or any ‘ requires 2.
So, try checking the wiring diagram in the data sheet and measure the output off load just to confirm it is producing -5V. I was getting a test reading of However, just to be sure I have a good understanding of what it is for: Your might be “blown”. Or you could use a 9V battery, or a power supply with an isolated ground connected “backwards”.
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.
7905C, 7905CT, 7905CV
If you wire up a negative voltage regulator backwards won’t it have to sink current? Don’t use the wrong part! That is the reason why I recommended the other part A voltage or voltage measurement is referenced to something, usually to ground.
In some cases, such as with a battery, you can simply reverse the connections to 7905cct a negative voltage.
