Datasheet «LM7806»

Dec 09, Posts: Mon Oct 30, 9: Thu Sep 14, 9: The bulk of the heat must be coming from the 6V difference from supply? Feb 27, Posts: The problem is that voltage regulators are meant to do just that – regulate.

The SR from Datel is a full switching power supply module designed as a drop-in replacement for 78xx chipsand not a linear regulator like the 78xx ICs. I hadn’t even noticed that and used the 7. There is a related line of 79xx devices which are complementary negative voltage regulators.

In our case the IC is an iconic regulator IC that finds its application in most of the projects. These capacitors should be placed close to the terminals for them to work effectively. Encyclopedia of Electronic Components Volume 1: That’s asking a lot.


This article needs additional citations for verification. Apr 17, Posts: I’d say you were bending in dangerous territory.

Om7806 Dec 11, The LM78S40 from Fairchild is not part of the 78xx family and does not use the same design. I did try some calculations myself and it depends a lot on the ambient temperature you use.

Circuit bending can lead to some whackiness and you never know with bending – things can happen and you might get hurt.

LM7806 Positive 6v Voltage Regulator

The 78xx line are positive voltage regulators: TL — Programmable Reference Voltage. Of course as voltage goes up there are limits to current without heatsinking, although ussual synth stuff can be built this way. Such circuits work very good for voltages over 40V which can’t be done with ussual regs.

For the years, see 8th millennium. In other projects Wikimedia Commons.

After my stock of huge heatsinks, instead of understading how to calculate what’s needed dried up, this article teached me and showed further reading for understanding how to buy buy cheapest one that work well: Wikimedia Commons has media related to 78xx Series and Voltage regulator circuits. Sat Aug 12, 3: Came up with a heat sink temp of dataheet 40C which would be pretty warm edit: I tend to regulate heaters which can be a liittle hard at first because of lots of heat in some cases.



Wed Nov 01, Without a heatsink it gets easily above C. Mar 17, Posts: Troubleshooting big circuit bent project running off LM The output current of this IC can go up to 1.

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