Great deal, you get MC, schottky diode, and a rewindable inductor.

You might consider a switching regulator. I choose a batch of -adj so i can get any voltage i need in future projects. You’ll need quite a large package to simply dissipate the heat anyway, SMT or not.

I’m now confused whether i ordered the right parts, there are so many regulators available! You can use Regulator Lk7805 cobine with zenner diode to make output stable at 5V. A lot less heat to worry about.

Question about voltage regulator to use. I’m looking for advise on SMD regulators. Or possibly an in-car USB charger which should provide a clean 5V and not take any space on your circuit board.


MarkT Brattain Member Posts: The MC is what is known as a “jelly bean” part. Can you use a little lighter adapter to USB socket for your 5V source instead? Heat sink will emd be an issue, my project uses only about mA.

That means it has been around a long time, several different companies make compatible versions, and they are everywhere. I have an Ultimaker and a 3D engraver.

Test equipment, replica and original sci fi props and costume pieces, and whatever else I feel like at the time. Question about SMD voltage regulator to use. I like this one because you can enter a variation in percent of the input voltage, and it automatically selects buck or boost.

But now i also saw other types of regulators, eg. The timer is another example of a jelly bean part. For an automotive project i am using a custom p project running at 5v.

In a car application, this will give you some immunity to the variability in the car’s DC voltage. The most important spec in an automotive application is the input maximum voltage – expect the car’s 12V to have big voltage spikes on it, many LDO regulators have a poor Vin max spec and are not suitable. RobvdVeer on Oct 01, For this i use a voltage regulator to convert the v down. Again, thanks but please read my question. Now with Unlimited Eagle board sizes!

Anyway, back to the OP’s topic. I should be able to solder a sot by hand. RobvdVeer Full Member Posts: CrossRoads on Oct 01, Still have it plugged in in the car so it wouldn’t rattle around in a cup holder.

On my breadboard prototype i use a lm An isolated DC-DC converter is a really good choice and worth thinking about – more tolerant of input voltage variations high and lowand fail-safe isolated.

Now i’m thinking about going SMD, i’ve ordered some lmadj. Even with 12V IN, there is a 7V voltage drop.

There are several Javascript calculators around the web. I ran my Duemilanove for several days powered from one of these as a test. Can you help me please?
