Tried google and checked stuff I have ordered...but maybe they are "fakes"?

What is this SUPPOSED to be?? Whole chip image? That may be a date code..

Small parts like that often have nearly useless markings on them, just a date/lot code and a shortened code that is listed in the datasheet - but for which there doesn't seem to be a lookup table for. ie, if you have the datasheet, you can see what it says is supposed to be written on the chip, but there's no list where you can take the number and find out what chip it is

Yup, a catch 22, you have to know which part it is before you can identify it...

If he ordered it, he's fine since he knows what it should be - just check the datasheet for the part, and it will tell you what the markings should look like; It's usually near the end of the datasheet in the section with part number and ordering info you normally don't bother reading.

Right, I think it might be some 5V regulators in SOT package...

I will wire one up later. Seems a bit odd that the markings don't give a hint. Did not know that so thanks for the heads up. Will teach me to be more careful and organise parts in future better...

Or leave them in their packaging/ESD bags until you are ready to use them.

I've got bags of little SMD LEDs,  I use a sharpie and mark their anode/cathode orientations on the bag so I don't have to keep looking up the datasheet.

What could be simpler than standardize on a triangle for the anode.

No technical PMs.
The last thing you did is where you should start looking.

The SMD LEDs are not marked like that. You have to interpret which laser etched bar or something else on the physical package represents the cathode, things like that. And no two seem alike.

Yeah, but you know manufacturers, everybody's got to do their own thing.
New 1284 Logger boards are in, waiting on a stencil.  9 days for boards from iteadstudio, got here so quick I wasn't ready with the stencils yet.
