It might be nice to mention to viewers that the adapter board used does not have a pad for the large central pin on the device and that this will substantially limit the power dissipation (and this maximum current)

you just did, but you are right

@4:45 those don't have the heat sink pad on them so it will limit the amount of current it can manage.

It is a linear regulator with thermal control. For a verification test it might be interesting to make a blinking circuit together with a light bulb. I once tried it out with the good old 7805.

Those chips are $10 apiece at the distributor. That Tic-Tac box is worth hundreds of dollars.

@@IMSAIGuy what a bargain! Tic tacs famously are 1.9 kcal per mint, and this chip in SSOP can dissipate 2.6 W (room temperature, giant ground plane). So at full power this chip can burn one tic tac's worth in 51 minutes. More seriously, this "3A" chip can only sustain 3A if the voltage drop is 866 mV or less. So forget about using it for 5V -> 3.3V conversion at 3A... it can only do that at 1.5 A, and only in a perfect thermal situation.

That package makes it difficult to use to its full current capacity. It could only work that high if used on a bd designed for it and oven soldered, something many hobbyists aren't up for. But for smaller loads, putting it on an adapter board makes it very usable.

i think i would be would be a little concerned that those molded PE bead boxes would lack any sort of ESD protection...am I overthinking it?

Um, actually, it's "JO-ANNE," not "Joanne's." Two women that were sisters. Sorry, couldn't resist... it's a stupid running joke at my house because my mom works there. And even she says "Joanne's" occasionally.
