[SOLVED] Component indentification SOT-23-6 markings S2CIA

[RatTrap85]

Have a SunEast SSD with critical sensitive information that must be recovered in house. From probing and testing my guess is that the bad component is either an LDO or a TVS Diode. Only markings are a 1 pin dot on the top left pin and the designation S2CIA. I have searched through every manufacturer I can think of to check for this marking style but no one seems to use this format. SunEast appears to be defunked, dead, or otherwise impossible to reach. Cannot find another SunEast SSD to canabalize for parts. I need to ID this component but am coming up empty. If anyone has any information that could aid me I would greatly appreciate it. Thank you so much for your help.

I have included pictures of it and of another one on the board that had easier to photograph markings.

Could be Seiko S-1721 Dual LDO 2V/1%

No, i think it is a Buck-SMPS IC.
Have a look here, it seems this is areference design with MAXIO MAS1102 SSD controller. Maybe you can get a different SSD as donator.
SOT23-5 seems a fixed-voltage-type Buck, while SOT23-6 is adjustable.

oh wow. Thank you so much. You are a life saver. If I may ask, how in the world did you find that? That is simply amazing. I will admit that when I posted that, it was a hail Mary play, and I held out little hope. I certainly had no expectation of an exact part match that I can use to cannibalize parts from. Thank you again.

I guess it isn't an exact part to cannibalize parts from. but more than enough data to go through to find the component on mouser/digi/shenzen. Thank you so much
