Can you use a little lighter adapter to USB socket for your 5V source instead? Still have it plugged in in the car so it wouldn’t rattle around in a cup holder. There are several Javascript calculators around the web.

But now i also saw other types of regulators, eg. Can you help me please? Question about voltage regulator to use. RobvdVeer Full Member Posts: You might consider a switching regulator. I choose a batch of -adj so i can get any voltage i need in future projects.

Question about SMD voltage regulator to use

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 lj7805 not suitable.

I ran my Duemilanove for several days powered from one of these as a test. RobvdVeer on Oct 01, Question about SMD voltage regulator to use.

That means it has been around a long time, several different companies make compatible versions, and they are everywhere. You’ll need quite a large package to simply dissipate the heat anyway, SMT or not. Now with Unlimited Eagle board sizes! I have an Ultimaker and a 3D engraver.

For an automotive project i am using a custom p project running amd 5v. Now i’m thinking about going SMD, i’ve ordered some lmadj.

CrossRoads on Oct 01, The MC is what is known as smx “jelly bean” part. Test equipment, replica and original sci fi props and costume pieces, and whatever else I feel like at the time. I’m looking for advise on SMD regulators. A lot less heat to worry about.

Again, thanks but please read my question. Great deal, you get MC, schottky diode, and a rewindable inductor.

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. MarkT Brattain Member Posts: Anyway, back to the OP’s topic.

Even with 12V IN, there lm7085 a 7V voltage drop. You can use Regulator LM cobine with zenner diode to make output stable at 5V. I should be able to solder a sot by hand.

78M05 – 7805 – (SMD TO-252/DPAK Package) – 5V Positive Voltage Regulator IC

For this i use a voltage regulator to convert the v down. Heat sink will not be an issue, my project uses only about mA. The timer is another example of a jelly bean part. On my breadboard prototype i use a lm I like this one because you can enter a variation in percent of the input voltage, and it automatically selects buck or boost. Or possibly an in-car USB charger which should provide a clean om7805 and not take any space on your circuit board.
