Sun Aug 13, 4: If I understood what I read around at all, I am needing to dissipate around 2W. Feb 27, Posts: Some devices provide slightly different voltages than usual, such as the LM78L62 6. Views Read Edit View history. According to a quick google, too hot would be about 50C to 60C. Here, the input voltage datasgeet be anywhere between 9VV, and the output voltage can be adjusted using the value of resistance R1 and R2. What do you guys think of this?

These capacitors should be placed close to the terminals for them to work effectively. Dedicated to experimental electro-acoustic and electronic music.

TL — Programmable Reference Voltage. 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 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 used 25C since that most likely matches the situation of sitting there testing out your new circuit with the chassis open and putting your finger on it to see if it’s getting hot.

The is the most common, as its regulated 5-volt supply provides a convenient power source for most TTL components. The problem is that voltage regulators are meant to do just that – regulate. I’ve never done any calculations myself and it’s not that easy as there are a lot of variables. Jan 14, Posts: There is a related line of 79xx devices which are complementary negative voltage regulators. From Wikipedia, the free encyclopedia.

Submitted by admin on 30 August They can be done with fets instead of datasheey which offer even lower power components. 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. Came up with a heat sink temp of about 40C which would be pretty warm edit: San Diego Audio files: Having trouble finding existing related topics at the moment, and other electronics forums touch on the subject but are often going over my head.

We just need two capacitors of vale 33uf and 0. Sun Aug 13, 1: Wed Nov 01, Sunny Oakland California Audio files: Mar 17, Posts: It works, but I measured about mA being drawn from the 6V line, at which the regulator gets too hot to touch very quickly.

Dec 09, Posts: The 78xx family is commonly used in electronic circuits requiring a regulated power supply due to their ease-of-use datahseet low cost. Cool Projects for Open Source Hardware. Voltage regulators are very common in electronic circuits. In our datasueet the IC is an iconic regulator IC that finds its application in most of the projects.

3-TERMINAL 1A POSITIVE VOLTAGE REGULATOR

Sat Aug 12, 3: The circuit bent part of the project itself only wants 6V. It is a TO package, currently using this little heat sink: Something else you might be able to do is reduce the current draw for the 6V section.

These devices support an input voltage anywhere from around 2. I did try some calculations myself and it depends a lot on the ambient temperature you use.

Troubleshooting big circuit bent project running off LM 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 dataeheet about right.

Please help improve this article by adding citations to reliable sources. This 7 Watts will be dissipated as heat. 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.
