Anyway, back to the OP’s topic. Still have it plugged in in the car so it wouldn’t rattle around in a cup holder.
I’m now confused whether ,m7805 ordered the right parts, there are so many regulators available! RobvdVeer on Oct 01, That means it has been around a long time, several different companies make compatible versions, and they are everywhere.
Question about SMD voltage regulator to use. MarkT Brattain Member Posts: I like this one because you can enter a variation in percent of the input voltage, and it automatically selects buck or boost. I ran my Duemilanove for several days powered from one of these as a test.
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. Now with Unlimited Eagle board sizes! Can you help me please? Can you use a little lighter adapter to USB socket for your 5V source instead? Great deal, you get MC, schottky diode, and a rewindable inductor. Or possibly an in-car USB charger which should provide a clean 5V and not take any space on your circuit board.
Heat sink will not be an issue, my project uses only about mA.
Question about SMD voltage regulator to use
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. I should be able to solder a sot by hand. The timer llm7805 another example of a jelly bean part. The MC is what is known as a “jelly bean” part.
Voltage Regulator 7805 SMD SOT223
Question about voltage regulator to use. You might consider a switching regulator.
You can use Regulator LM cobine with zenner diode to make output stable at 5V. RobvdVeer Full Member Posts: Again, thanks but please read my sm.
For this i use a voltage regulator to convert the v down. For an automotive project i am using a custom p project running at 5v. I’m looking for advise on SMD regulators. Even with 12V IN, there is a 7V voltage drop.
78M05 – 7805 – (SMD TO-252/DPAK Package) – 5V Positive Voltage Regulator IC
I choose a batch of -adj so i can get any voltage i need in future projects. Test equipment, replica and original sci fi props and costume pieces, and whatever else I feel like at the time. CrossRoads on Oct 01, In a car application, this will give you some immunity to the variability in the car’s DC voltage.
