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. Jan 14, Posts: The LM78S40 from Fairchild is not part of the 78xx family and does not use the same design. We just need two capacitors of vale 33uf and 0. 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.

But, the IC suffers from heavy heat loss hence a Heat sink is recommended for projects that consume more current.

The output current of this IC can go up to 1. Mon Oct 30, 9: Display darasheet from previous: Encyclopedia of Electronic Components Volume 1: Moon Base Audio files: This article needs additional citations for verification.

One should always consider the maximum possible working temperature of the circuit: I’ve never done any calculations myself and it’s not that easy as there are a lot of variables.

That’s asking a lot. San Diego Audio files: This is a typical application circuit of the IC. Sun Aug 13, 1: Mar 17, Posts: Please support our site. TL — Programmable Reference Voltage.

Also they should be of ceramic type, since ceramic capacitors are faster than electrolytic. These capacitors should be placed close to the terminals for them to work effectively.

But ya, at some point the different ranges need to be taken into consideration before you pack it in a chassis and expect it to work over a variety of conditions. I tend to regulate dafasheet which can be a liittle hard at first because of lots of heat in some cases.

Such circuits work very good for voltages over 40V which can’t be done with ussual regs. The input capacitor 0. Cool Projects for Open Source Hardware. What do you guys think of this?

They provide a constant output voltage for a varied input voltage. 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. This 7 Watts will be dissipated as heat.
