Need help for SMD

[MT]

Anyone could you please advise SMD Q5 "LL" SOT-23 on the picture.  What's it.?  I try to find on SMD book.  It looks the pinout un-normal.  This is voltage converter.   Is it transistor or jfet or regulate.

I could be mistaken, but the markings look like it says "720", which if that's the case, then it's likely this: https://www.diodes.com/assets/Datasheets/FMMT720.pdf
