Get am LM it is a TO case regulator just like the but it will work down to a.

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. At the end of stage 1 which involves building is ‘a simple linear regulator that provides the -5V power supply’.

Many variants of the 79L05 and need a minimum load, otherwise they produce a too high absolute value output voltage.

I am assembling a metal detector kit of parts. Home Questions Tags Users Unanswered.

LM CT: Linear voltage regulator -5V TO at reichelt elektronik

Dstasheet not simply buy another U1 79L The voltage can be positive or negative or AC, which swings both positive and negative. 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.

For example, many op-amp circuits require both a positive and negative supply. You didn’t damage it as it is protected for reverse insertion internally. Email Required, but never shown. Docedison on Jun 20, That is the reason why I recommended the other part Ddatasheet clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.

AS I said it is a poor one to be used only in dire circumstances and only as a last choice. Batteries could be smaller fewer cells and last datxsheet.

I’ve done it once in 50 years and it was a bad move then, never again. Is there w way I can salvage my negative resistors to steadily output 5v? Read times previous topic – next topic. Lol, thanks for your reply ratasheet, I’ll take note of that.

7905C, 7905CT, 7905CV

Dstasheet more comprehensible than post And more fun than post 7;- first OP case is fine. If you wire up a negative voltage regulator backwards won’t it have to sink current? Or you could use a 9V battery, or a power supply with an isolated ground connected “backwards”.

Is it as simple as reversing the polarity? Sign up using Email and Password.

difference between a negative and a positive voltage regulator?

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. Thanks for your replies! Don’t use the wrong part!

What is the use of negative regulators?

Step one operates the 79L05 completely unloaded, which can cause Your might be “blown”. I hope this is clear. Andy aka k 10 Very much the last choice you should make.

So what’s the difference between the 2? Some audio circuits use two 9V batteries 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, 790c5t checking the wiring diagram in the data sheet and measure the output off load just to confirm it is producing -5V.

Have at it with that one. So I have concluded that I should replace the voltage regulator U1 79L The answer for difference between a negative and a positive voltage regulator You’d need a negative supply to test it. I was getting a test reading of Actually the pin out for both 78 and 79 devices is easy to remember. Post datashheet a guest Name. Under certain circumstances it Might work but there will always be those reversed polarity issued there.

If with a 1mA load 5k resistor the voltage drops to -5V, your chip is OK. However, just to be sure I have a good understanding of what it is for:
