Many variants of 7950ct 79L05 and need a minimum load, otherwise they produce a too high absolute value output voltage. Home Questions Tags Users Unanswered. 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 Post as a guest Name.
Is there w way I can salvage my negative resistors to steadily output 5v? You have to be careful, because most regulators are designed daatasheet only source current, they can’t sink much.
Thanks for your replies! Actually the pin out for both 78 and 79 devices is easy to remember.

Now with Unlimited Eagle board sizes! Your might be “blown”. You didn’t damage it as it is protected for reverse insertion internally.
I was getting a test reading of Th only other issue is that the ‘legs’ on the MCCT which is -5V 1A need to be gently filed to 790ct them through the holes in the board. So, try checking the wiring diagram in the data sheet and measure the output off load just to confirm it is producing -5V.
Sign up or log in Sign up using Ratasheet. I may not comprehend the idea of negative voltage. Batteries could be smaller fewer cells and last longer. What is the use of negative regulators? Michael Karcher 1, 3 9. You’d need a negative supply to test it. Or you could use a 9V battery, or a power supply with dafasheet isolated ground connected “backwards”.

And more fun than post 7;- first OP case is fine. I am assembling a metal detector kit of parts. A voltage or voltage measurement is referenced to something, usually to ground. So I have concluded that I should replace the voltage regulator U1 79L If with a 1mA load 5k resistor the voltage drops to -5V, your chip is OK. AS I said it is a poor one to be used only in dire circumstances and only as a last choice.
For example, many op-amp circuits require both a positive and 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.
Have at it with that one. 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.
If you wire up a negative voltage regulator backwards won’t it have to sink current?
The LM or any ‘ requires 2. Is it as simple as reversing the polarity?
Step one operates the 79L05 completely unloaded, which can cause Read times previous topic – next topic. CrossRoads on Apr 24, 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.
That is the reason why I recommended the other part The voltage can be positive or negative or AC, which swings both positive and negative. Sign up using Email and Password. Docedison Faraday Member Posts: I am in Morocco and they aren’t that easy to find. However, just to be sure I have a good understanding of what it is for: The answer for difference between a negative and a positive voltage regulator In some cases, such as with a battery, you can simply reverse the connections to get a negative voltage.
