LM 7905 CT

I hope this is clear. Read times previous topic – next topic.

Docedison on Jun 20, AS I said it is a poor one to be used only in dire circumstances and only as a last choice. I am assembling a metal detector kit of parts.

It’s there to ensure that no more than 5 volts gets sunk into ground. So, try checking the wiring diagram in the data sheet and measure the output off load just to confirm it is producing -5V.

I am in Morocco and they aren’t that easy to find. In some cases, such as with a battery, you can simply reverse the connections to get a negative voltage.

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. Email Required, vatasheet never shown. Have at it with that one. And more comprehensible than post Th only other issue is that the ‘legs’ on the Datasheet which is -5V 1A need to be gently filed to allow them through the holes in the board.

If with a 1mA load 5k resistor the voltage drops to -5V, your chip is OK. Sign up or log in Sign up using Google.

difference between a negative and a positive voltage regulator?

Under certain circumstances it Might work but there will always be those reversed polarity issued there. If you wire up a negative voltage regulator backwards won’t it have to sink current? Home Questions Tags Users Unanswered. At the end of stage 1 which involves building is ‘a simple linear regulator that provides the -5V power supply’.

That is the reason why I recommended the other part For example, many op-amp circuits require both a positive and negative supply. However, just to be sure I have a good understanding of what it is for: I may not comprehend the idea of negative voltage.

Is there w way I can salvage my negative resistors to steadily output 5v? The voltage can be positive 79905ct negative or AC, which swings both positive and negative. Some audio circuits use two 9V batteries Or you could use a 9V battery, or a power supply with an isolated ground connected “backwards”.


You didn’t damage it as it is protected for reverse insertion internally.

So what’s the difference between the 2? CrossRoads on Apr 24, Your might be “blown”. Actually the pin out for both 78 and 79 devices is easy to remember. The answer for difference between a negative and a positive voltage regulator 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.

Pin 1 is most positive voltage 0V on a 79xx and datasheer voltage on a 78xx Pin 2 is most negative voltage 0V on a 78xx and input voltage on daatasheet 79xx The can naturally replace the 79L
