LM1117AL (18A PDTQ)

[Buk]

I'm trying to find a datsheet for the subject labelled part; but all datasheets lists so many variations that I cannot work out which one.
(I'd post an photo but I cannot capture the text. I can only just make it out by tilting the thing at an angle to the light.)

It looks like this:

the main body is 6.2 x 3.1 mm.

ti.com use this link.
1) Go to Digikey.com and type LM1117 in the search window. Mouser.com or any big supplier.
2) If you know it was made by TI go to TI.COM and search.

Go to Digikey.com and type LM1117 in the search window.

Similar no results at Mouser.

If I omit the AL, then 124 results none of which are AL.

I finally managed to get the text visible in a photo:

Unfortunately, that doesn't help much. There are so many listed, but none with the "18A PDTQ" bit. so It means I have to guess that the "18A" bit means 1.8V, which if true is decidedly counter intuative.

It obviously isn't 18 amps, as these devices are either 0.8A or 1.0A depending on the presence of the A : KD1117AL

Further cluebats sought.

The last four characters are a manufacturing site / date or batch code and not part of the device number.

Both the ST and UTC versions use 18 or possibly 1.8 to specify 1.8V output.
