Electronic – Need help identifying pcb component

componentspcb

I was trying to repair the main board of a monitor (Samsung S27B750V), and after a few hours I did something I shouldn’t have, and blew this component.
I have tried to search for this but I am unable to find anything about it. Need to have it replaced. It reads “SOZ B21” I believe.

Perhaps there is an alternative to it?
I have a lot of old PCB's laying around, but have never seen this kind on any of them.

EDIT:
After uploading both photos I see they have different text in the middle.

Dimensions are 4.3 x 2.4 mm

My best guess it's an ABLIC S-1172B33-U5T1x low dropout regulator (3.3V).

S1172 series LDO

SOZ denotes the 3.3 V version and B21 is the lot number.
