Topic: can i solder a linear V regulator flat. (Read 781 times) previous topic - next topic


@CrossRoads yeah thats exactly what i was looking at, the Unos regulator and i did notice the additional pad it had underneath

@KE7GKP  ah thanks for the info! im going to pick up a couple of those at mouser.

another question, you know those capacitors on the Uno with the silver casing and rather short stubby looking, what are those type of capacitors called? I like them
I could print the Arduino logo on a box of cereal and sell it as "Arduin-O's"

Look for this kind of part at digkey

Capacitor, 100uF, Aluminum, Radial Can-SMD, 6.3mm,25V   EEE-1EA101XP   digikey P/N PCE3898CT-ND

Good call. I have never used one myself that isn't ground but that does not rule out the possibility. Maybe it's a euro thing. :)

No its a chip-design thing - the metal tab is normally bonded to the substrate of the IC.  It depends on the process whether this is the most negative or most positive part of the circuit.  For bipolar transistors it is usually the collector, and for power MOSFETs it is always the drain.
