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

It’s datasheeet to ensure that no more than 5 volts gets sunk into ground. Home Questions Tags Users Unanswered. Why not simply buy another U1 79L Your might be “blown”.

AS I said it is a poor one to be used only in dire circumstances and only as a last choice. Sign up using Email and Password.

If you wire up a negative voltage regulator backwards won’t it have to sink current?

Have at it with that one.

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. So, try checking the wiring diagram in the data sheet and measure the output off load just to confirm it is producing -5V.

The LM or any ‘ requires 2. Under certain circumstances it Might work but there will always be those reversed polarity issued there. And more comprehensible than post That is datashfet reason why I recommended the other part Step one operates the 79L05 completely unloaded, which can cause And more fun than post 7;- first OP case is fine.

I was getting a test reading of Read times previous topic – next topic. 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.

In some cases, such as with a battery, you can simply reverse the connections to get a negative voltage. Discussion has been re-started by post 7.

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. 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. If with a 1mA load 5k resistor the voltage drops to -5V, your chip is OK. Andy aka k 10 Batteries could be smaller fewer cells and last longer.

So I have concluded that I should replace the voltage regulator U1 79L 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. Don’t use the wrong part!

A voltage or voltage measurement is referenced to something, usually to ground. Thanks for your replies!

The voltage can be positive or negative or AC, which swings both positive and negative. What is the use of negative regulators? Very much the last choice you should make.
