I hadn’t even noticed that and used the 7. Came up with a heat sink temp of about 40C which would be pretty warm edit: Something else you might be able to do is reduce the current draw for the 6V section.

They provide a constant output voltage for a varied input voltage. Display posts from previous: At 9V supply the regulator doesn’t get hot enough to burn you, but still uncomfortably hot with the current heat sink.

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 I’d say you were bending in dangerous territory. Jan 14, Posts: This IC can also act as an adjustable output voltage regulator, meaning you can also control the output voltage for your desired value using the below circuit.

This is a typical application circuit of the IC. For the years, see 8th millennium. Having trouble finding existing related topics at the datasheett, and other electronics forums datasueet on the subject but are dataxheet going over my head. These devices support an input voltage anywhere from around 2.

It is a component in switching regulator designs and is not a linear regulator like other 78xx devices. 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 datasheett and given the very intellectual back and forth you likely know whats up but to any folks still leaning Live streaming at radio. The is the most common, as its regulated 5-volt supply provides a convenient power source for most TTL components.

Of course as datashewt goes up there are limits to current without heatsinking, although ussual synth stuff can be built this way. If I understood what I read around at all, I am needing to dissipate around 2W. Some devices provide slightly different voltages than usual, such as the LM78L62 6. Here, the input voltage can be anywhere between 9VV, and the output voltage can be adjusted using the value of resistance R1 and R2.

It is a TO package, currently using this little heat sink: Sun Aug 13, 2: Views Read Edit View history.

But, the IC suffers from heavy heat loss hence a Heat sink is recommended for projects that consume more current. According to datssheet quick google, too lm7860 would be about 50C to 60C. A DC-DC converter might indeed not be such a bad idea it’s definitely more efficient, although it could cause some unwanted noise. Sat Aug 12, Apr 17, Posts: Fri Aug 11, 8: A quick search led me to this page which might be helpful and shows how many variables there are.

Such circuits work very good for voltages over 40V which can’t be done with ussual regs. Sun Aug 13, 1: There is a related line of 79xx devices which are complementary negative voltage regulators.

3-TERMINAL 1A POSITIVE VOLTAGE REGULATOR

The value can be calculated using the below formulae. The output current of this IC can go up to 1. We just need two capacitors of datashet 33uf and 0. Retrieved from ” https: The 78xx family is commonly used in electronic circuits requiring a regulated power supply due to their ease-of-use and low cost.

Can anyone tell me how to calculate?

In other projects Wikimedia Commons. Feb 27, Posts: 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. This 7 Watts will be dissipated datashret heat.
