I had something interesting happen to me... I got some simple lm705 regulators from TI and hooked them into a preamp powersupply and they immediately blew,,, turns out that the lm705 from TI doesn't have the same pin out as the lm705 from any of my schematics. Gotta make sure to double check the data sheet!

Edit- Sorry Bjorn they are the 7805... just going from memory here so forgot the "8" in there.

You did not confuse 7805 with 705?

I recently got some samples for work from TI... expecting 3.0volt LDOs in SOT-23...

Sure as heck wasnt, the bag was labeled as the parts I wanted, the chip wasnt. Placed another sample order and all was well.

So even straight from the source stuff can be screwy.
