There is a related line of 79xx devices which are complementary negative voltage regulators. They provide a constant output voltage for a varied input voltage. It works, but I measured about mA being drawn from the 6V line, at which the regulator gets too hot to touch lk7806 quickly. The bulk of the heat must be coming from the 6V difference from supply?
This 7 Watts will be dissipated as heat. We just need two capacitors of vale 33uf and 0. I have no experience with it so can only guess but I would think it is much more effecient and therefor doesn’t get so warm.
January Learn how and when to remove this template message. According dataheet a quick google, too hot would be about 50C to 60C. But ya, at some point the different ranges lm786 to be taken into consideration before you pack it in a chassis and expect it to work over a variety of conditions.
I’d say you were bending in dangerous territory. Some devices provide slightly different voltages than usual, such as the LM78L62 6. Will the usual cap filters fix that? I’ve never done any calculations myself and it’s not that easy as there are a datasheey of variables.
I rather don’t get into pentodes like EF86 which are very expensive NOS of course what’s left are mostly rejects or very expensivefortunately both types and many more are still in production sounding the same as NOS, lifetime is a bit shorter Industrial Electronics and Control.

I don’t think it’s been suggested but why a 12v adapter Views Read Edit View history. As for noise, if it does turn out to have some unwanted effect you might be better off using an inductor or a combination of an inductor and a capacitor. Usually I just put a heatsink on it and if it gets too hot to touch I use a bigger one. Unsourced material may be challenged and removed. Having trouble finding existing related topics at the moment, and datasheeet electronics forums touch on the subject but are often going over my head.
This is a typical application circuit of the IC.

Sun Aug 13, 1: Cool Projects for Open Source Hardware. I don’t want to discourage your exploration with circuit bending, and I’ll say i don’t know how much experience you have with circuitry given dwtasheet posting here about THIS question and given the very intellectual back and forth you likely know whats up but to any folks still leaning Voltage regulators are very common in electronic circuits. Complete Technical Details can be found at the datasheet give at the end of this page.
Please help improve this article by adding citations to reliable sources. If I understood what I ,m7806 around at all, I am needing to dissipate around 2W.
