Most of the regulators I got were 2.8v, not 3.3v. The one I did find that did 3.3 dropped to 3.08 after a couple weeks.

24 out of 25 were not within manufacturer's spec of 3.3v +/- 3%. Of those, 20/25 were below 2.65v or lower (20% low!!!), one was 3.66v, and three were around 2.8v.This is wildly unacceptable for a component whose primary (and virtually only) function is to regulate input voltage to the specified output voltage.This will be the last time I buy electrical components like this on Amazon. Quality control is non-existent.

Work great and only uses microamps of energy like stated. Happy that I found out about these.

I really expected high quality and reliability. Unfortunately the first ldo out of the bag outputed ~2.82v instead of 3.3v. The second one did output 3.3v - great!. Then I tested another 6 items, all failed, usually outputting 2.8v but sometimes more or less depending on the input. Tested each with both 3.3v input. and 5v input.1 out of 8 is not a good ratio (and a waste of my time), now I have to find another ldo.I really don't understand, I thought microchip technology was a quality companyEdit: I ordered another of the same item from the same supplier and all 25 checked out fine. The first order must have been a bad batch, the supplier quickly refunded me and the second batch was perfect.
