If with a 1mA load 5k resistor the voltage drops to -5V, your chip is OK. Home Questions Tags Users Unanswered.

MCCT datasheet & applicatoin notes – Datasheet Archive

The voltage can be positive or negative or AC, which swings both positive and negative. Sign up or log in Sign up using Google. 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. 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.

For example, many op-amp circuits require both a positive and negative supply. And more comprehensible than post That is the reason why I recommended the other part You didn’t damage it as it is protected for reverse insertion internally.

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. Michael Karcher 1, 3 9. Batteries could be smaller fewer cells and last longer.

difference between a negative and a positive voltage regulator?

However, just to be sure I have a good understanding of what it is for: Now with Unlimited Eagle board sizes! Docedison Faraday Member Posts: I was getting a test reading of I may not comprehend the idea of negative voltage.

Thanks for your replies! And more fun than post 7;- first OP case is fine. So, try checking the wiring diagram in the data ratasheet and measure the output off load just to confirm it is producing -5V. A voltage or voltage measurement is referenced to something, usually to ground. Step one operates the 79L05 completely unloaded, which can cause Or you could use a 9V battery, or a power supply with an isolated datashset connected “backwards”.

Actually the pin out for both 78 and 79 devices is easy to remember. What is the use of negative regulators?

7905C, 7905CT, 7905CV

Get am LM it is a TO case regulator just like the but it will work down to a. If you have the space and have checked the pinout 79xx negative regulator pinout is 790ct the same as 78xx positive regulator pinout then go ahead. Your might be “blown”.

Don’t use the wrong part!

I’ve done it once in 50 years and it was a bad move then, never datazheet.

Lol, thanks for your reply doc, I’ll take note of that. Eatasheet need a negative supply to test it. I hope this is clear. Discussion has been re-started by post 7. 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.

Have at 790c5t with that one. Andy aka k 10 By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. Is it as simple as reversing the polarity?

If you wire up a negative voltage regulator backwards won’t it have to sink current? So what’s the difference between the 2?

I am assembling a metal detector kit of parts. Some audio circuits use two 9V batteries
