Hey Peeps

I was wondering if anyone knew of any simple to understand tutorials about voltage regulators - at least, I think that is what I have.
I bought this component having seen something similar on a circuit schematic and thought it was quite important, so I got some. It is a LM319T Adjustable Positive Regulator.

If not a tutorial, just a quick ... what is it ? what's it for !? and how do I use it ? I wanna step down from 6v to 5v for my test circuits and THINK this is what I need. I know it's only 1v difference but I wanna learn about it nevertheless.

Thanks in advance

- Alex.

Hi Alex
You can get the data sheet for it (and many other semics) from here:

And this tutorial is from this site:

Happs,


Is it possible that the part number of the device you have is an LM317t? I know that there is a 3 terminal adjustable positive voltage by that part number. I looked up the LM319 and it looks like that is the part number for a comparator, I think.

Since you are looking to regulate 6V to 5V, you will need to make sure that whatever regulator you use is an LDO or low drop out regulator. An LDO regulator will work with a very small difference between the input voltage and the output voltage.

Hey guys

Thanks for the information :) Much appreciated. I figured it all out now :D
