Help identification component on water damaged MSI 1070 Gaming X GPU

[ZoOLf]

Hi gents,

so i recovered a liquide damaged GPU (MSI 1070 Gaaming X) i try to fix it,
the corrosion is so bad that it ate some component's pads.
some are easy identifiable, others are not, from a similaire Boardview (Msi 1080GTX attached) I got some info:

1-in boardview the component is named SOT23-5 no other info:

from the pic we can see marking L1C9.
no datasheet available and I cant find where to purchase it, What other Ref can I use instead.

2-not available in the boardview but i guess its Sot23 (marking 2A. and N symbole)

same no datasheet no info where to get it or something similaire.
you can see in the pic also the component L1117LG which i found it easily in aliexpress.

3- in boardview the componant is named 0.807v a quick googling gave me Sot23-8 :

marking ADPG also no info where to get it.

so any idea with what component i can use instead ?

the MSI 1080 boardveiw


PS: a high res of the PCB pic

The part marked ADPG has a vertical bar on the left, it a Monlithic Power part - https://www.badcaps.net/forum/showpo...85&postcount=3 .The last digit is a year code,so the part number is ADP

Heres the datasheet https://www.monolithicpower.com/en/d...ocument_id/342 MP1475DJ
