You have to be careful, because most regulators are designed to only source current, they can’t sink much. In some cases, such as with a battery, you can simply reverse the connections to get a negative voltage.

You didn’t damage it as it is protected for reverse insertion internally. The LM or any ‘ requires 2. Actually the pin out for both 78 and 79 devices is easy to remember. Many variants of the 79L05 and need a minimum load, otherwise they produce a too high absolute value output voltage.

For example, many op-amp circuits require both a positive and negative supply. I may not comprehend the idea of negative voltage.

Andy aka k 10 So I have concluded that I should replace the voltage regulator U1 79L 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. 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.

Get am LM it is a TO case regulator just like the but it will work down to a. The answer for difference between a negative and a positive voltage regulator What is the use of negative regulators?

Voltage Regulator IC | Datasheet

Pin 1 is most positive voltage 0V on a 79xx and input voltage on a 78xx Pin 2 7905cg most negative voltage 0V on a 78xx and input voltage on a 79xx The can naturally replace the 79L Docedison Faraday Member Posts: So, try checking the wiring diagram in the data sheet and measure the output off load just to confirm it is producing -5V.

I hope this is clear.

If with a 1mA load 5k resistor the voltage drops to -5V, your chip is OK. Or you could use a 9V battery, or a power supply with an isolated ground connected “backwards”. And more fun than post 7;- first OP case is fine.

Your might be “blown”. Email Required, but never shown. I was getting a test reading of Sign up using Facebook. Some audio circuits use two 9V batteries Read times previous topic – next topic.

That is the reason why I recommended the other part And more comprehensible than post Now with Unlimited Eagle board sizes! Is there w way I can salvage my negative resistors to steadily output 5v?
