The LM or any ‘ requires 2. You didn’t damage it as it is protected for reverse insertion internally.

Is there w way I can salvage my negative resistors to steadily output 5v?

7905C, 7905CT, 7905CV

Read times previous topic – next topic. So what’s the difference between the 2? Some audio circuits use two 9V batteries Get am LM it is a TO case regulator just like the but it will work down to a.

Actually the pin out for both 78 and 79 devices is easy to remember. Docedison on Jun 20, Lol, thanks for your reply doc, I’ll take note of that. However, just to be sure I have a good understanding of what it is for: 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.

Many variants of the 79L05 and need a minimum load, otherwise they produce a too high absolute value output voltage. Very much the last choice you should make. Post as a guest Name.

Under certain circumstances it Might work but there will always be those reversed polarity issued there. Your might be “blown”. Home Questions Tags Users Unanswered.

difference between a negative and a positive voltage regulator?

In some cases, such as with a battery, you can simply reverse the connections to get a negative voltage. I hope this is clear. I am assembling a metal detector kit of parts.

So I have concluded that I should replace the voltage regulator U1 79L Pin 1 is most daatsheet 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 Is it as simple as reversing the polarity?

You’d need a negative supply to test it. 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.

Don’t use the wrong part! CrossRoads on Apr 24, So, try checking the wiring diagram in the data sheet and measure the output off load just to confirm it is producing -5V. What is the use of negative regulators? Sign up using Email and Password.

Email Required, but never shown. If you are building a “bi-polar” power supply, you might use a datasheeh regulate the positive voltage, and a to regulate the negative voltage. Andy aka k 10
