I’m now confused whether i ordered the right parts, there are so many regulators available!

Best Price Voltage Regulator SMD SOT | UGE Electronics

I choose a batch of -adj so i can get any voltage i need in future projects. A lot less heat to worry about.

You can use Regulator LM cobine with zenner diode to make output stable at 5V. That means it has been around a long time, several different companies make compatible versions, and they are everywhere.

For this i use a voltage regulator to convert the v down. On my breadboard ,m7805 i use a lm Now i’m thinking about going SMD, i’ve ordered some lmadj. For an automotive project i am using a custom p project running at 5v. Heat sink will not be an issue, my project uses only about mA. Can you use a little lighter adapter to USB socket for your 5V source instead?


Now with Unlimited Eagle board sizes! Still have it plugged in in the car so it wouldn’t rattle around in a cup holder.

I ran my Duemilanove for several days powered from one of these as a test. I’m looking for advise on SMD regulators.

Question about voltage regulator to use. Question about SMD voltage regulator to use. Or possibly an in-car USB charger which should provide a clean 5V and not take any space on your circuit board. But now i also saw other types of regulators, eg. Anyway, back to the OP’s topic. There are several Javascript calculators around the web. In a car application, this will give you some immunity to the variability in the car’s DC voltage.

Test equipment, replica and original sci fi props and costume pieces, and whatever else I feel like at the time. I should be able to solder a sot by hand. The MC is what is known as a “jelly bean” part. You might consider a switching regulator.

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

I have an Ultimaker and a 3D engraver. I like this one because you can enter a variation in percent of the input voltage, and it automatically selects buck or boost. RobvdVeer on Oct 01, MarkT Brattain Member Posts: CrossRoads on Oct 01, Great deal, you get MC, schottky diode, and a rewindable inductor.


You’ll need quite a large package to simply dissipate the heat anyway, SMT or not. The timer is another example of a jelly bean part. 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.

Can you help me please? 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. Again, thanks but please read my question. Even with 12V IN, there is a 7V voltage drop. RobvdVeer Full Member Posts:
