Wed Nov 01, January Learn how and when to remove this template message. I tend to regulate heaters which can be a liittle hard at first because of lots of heat in some cases.

Moon Base Audio files: The LM78S40 from Fairchild is not part of the 78xx family and does not use the same design. I did manage to drop to 9V supply – the higher voltage was originally to suit a Synthrotek Vac-Pak CV circuit, but they work fine on 9V.
Getting right heatsink seems datasheeet more difficult than building good psu, although i found one has to understand only a few basics to get sufficient heatsink. LM Voltage Regulator Datasheet.
Encyclopedia of Electronic Components Volume 1: Fri Aug 11, 8: Sun Aug 13, 1: What do you guys think of this?
The output current of this IC can go up to 1. Articles needing additional references from Datasjeet All articles needing additional references. Voltage regulators are very common in electronic circuits.
Please help improve this article by adding citations to reliable sources. Without a heatsink it gets easily above C. From Wikipedia, the free encyclopedia.
:: View topic – Voltage Regulator Overheating – Heat Sink Needs?
Display posts from previous: I don’t think it’s been suggested but why a 12v adapter The reason is because without a blower the temperature in the neighbourhood of the heat sink is higher than in the rest of the room. Apr 17, Posts: View unread posts View new posts in the last week Mark the topic unread:: Will the usual cap filters fix that?
It works, but I measured about mA being drawn from the 6V line, at which the regulator gets too hot to touch very quickly. This is a typical application circuit of the IC.
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: But ya, at some point the different ranges need to ddatasheet taken into consideration before you pack it in a chassis and expect it to work over a variety of conditions.
The problem is that voltage regulators are meant to do just that – regulate.
