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 This is a typical application circuit of the IC. Wed Nov 01, Will the usual cap filters fix that? Views Read Edit View history.

It is a Datashwet package, currently using this little heat sink: It is a component in switching regulator designs and is not a linear regulator like other 78xx devices.

I’ve never done any calculations myself and it’s not that easy as there are a lot of variables.

They provide a constant output voltage for a varied input voltage. Sun Aug 13, 2: I played around with the calculator in PHOBoS’ link with the numbers from the heat sink and LM data sheet and the 2W of dissipation sounds about right.

Display posts from previous: Such circuits work very good for voltages over 40V which can’t be done with ussual regs. Having trouble finding ml7806 related topics at the moment, and other electronics forums touch on the subject but are often going over my head.


What do you guys think of this? This 7 Watts will be dissipated as heat. Sat Aug 12, 3: At 9V supply the regulator doesn’t get hot enough to burn you, but still uncomfortably hot with the current heat sink.

I did try some calculations myself and it depends a lot on the ambient temperature you use. Cool Projects for Open Source Hardware. Sunny Oakland California Audio files: But, the IC suffers from heavy heat loss hence a Heat sink is recommended for projects that consume more current. Dec 09, Posts: Datqsheet say you were bending in dangerous territory.

In other projects Wikimedia Commons. Sun Aug 13, 1: One should always consider the maximum possible working temperature of the circuit: Usually I just put a heatsink on it and if it gets too hot to touch I use a bigger one.

Feb 27, Posts: Some devices provide slightly different voltages than usual, such as the LM78L62 6. Tue Dec 11, We just need two capacitors of vale 33uf and 0.

The input capacitor 0. That’s asking a lot. By using this site, you agree to the Terms of Use and Privacy Policy. Please support our site. The is the most common, as its regulated 5-volt supply provides a convenient power source for most TTL components.

Getting right heatsink seems like more difficult than building good psu, although i found one has to understand only a few basics to get sufficient heatsink. I hadn’t even noticed that and used the 7.

Please help improve this article by adding citations to reliable sources. San Diego Audio files: Also they should be of ceramic type, since ceramic capacitors are faster than electrolytic. 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 your posting here about THIS question and given the very intellectual back and forth you likely know whats up but to any folks lm706 leaning Mon Oct 30, 9: Voltage regulators are very common in electronic circuits.

The problem is that voltage regulators are meant to do just that – regulate.
