Identify or equivalent SMD S4QB


I’m trying to identify what this component is or a possible substitute so I can make an order. I have looked everywhere and I can’t seem to find anything. This is my last resort and I hope someone can help. Thanks in advance!

Hi iBringsTheRuckus,

This part is likely from Microne.
An LDO, if I may guess.
Microne do not show the marking codes on their datasheets, thus you may need to ask them directly.

The closest code could find is “S2QB”.

Awesome!! Thanks so much!! It’s very unfortunate that digikey doesn’t carry them. I would like to add that it looks like S4 is 1.2v and the last 2 letters are random. For anyone that stumbles on this, the part # is me6211c12m5g. I hope this will fix my problem and isn’t another component causing it to get hot, but will report back. Thanks again!!
