Thanks for your replies! Have at it with that one. Or 7905cg could use a 9V battery, or a power supply with an isolated ground connected “backwards”. Get am LM it is a TO case regulator just like the but it will work down to a. Is it as simple as reversing the polarity?

AS I said it is a poor one to be used only in dire circumstances and only as a last choice. Actually the pin out for both 78 and 79 devices is easy to remember.

A voltage or voltage measurement is referenced to something, usually to ground. The LM or any ‘ requires 2. Why not simply buy another U1 79L 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. I am assembling a metal detector kit of parts.

Docedison Faraday Member Posts: I am in Morocco and they aren’t that easy to find. Lol, thanks for your reply doc, I’ll take note of that. Some audio circuits use two 9V batteries Many variants of the 79L05 and need a minimum load, otherwise they produce dayasheet too high absolute value output voltage.

You have to be careful, because most datqsheet are designed to only source current, they can’t sink much. That is the reason why I recommended the other part If you wire up a negative voltage regulator backwards won’t it have to sink current?

Your might be “blown”.

I was getting a datssheet reading of Is there w way I can salvage my negative resistors to steadily output 5v?

Step one operates the 79L05 completely unloaded, which can cause So what’s the difference between the 2? I may not comprehend the idea of negative voltage.

And more comprehensible than post What is the use of dataheet regulators? 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.

Selling C, CT, CV with C, CT, CV Datasheet PDF of these parts.

I’ve done it once in 50 dwtasheet and it was a bad move then, never again. Very much the last choice you should make. And more fun than post 7;- first OP case is fine.

If with a 1mA load 5k resistor the voltage drops to -5V, your chip is OK. At the end of stage 1 which involves building is ‘a simple linear regulator that provides the -5V power supply’.

You didn’t damage it as it is protected for reverse insertion internally. You’d need a negative supply to test it.

In some cases, such as with a battery, you can simply reverse the connections to get a negative voltage. I hope this is clear.

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. For example, many op-amp circuits require both a positive and negative supply. The answer for difference between a negative and a positive voltage regulator 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.
