Hi,
Sorry but I was away for a few days. Thank you all for the answer.
Ok, CHAXX is SGM2033-ADJ
In my case R1=110k (05D) and R2=39k (393) it results that Vout = 1.2 x (1+R1/R2) = 4.6V
Locally I can't find a supplier for this IC, but I think I can use AP2210K-ADJTRG1 without any modification, having Vout= 1.24 x (1+R1/R2)= 4.74v. Another option would be to use AP2210K-5.0TRG1
Which one do you think would be better use?

No inductor
It is linear
I think is similar with SL9650 - ADJ, but not sure about Vout value

Owon HDS2202S oscilloscope
Hi all,
I have this OWON HDS2202S oscilloscope that worked fine until it was used with the wrong probes mounted in the wrong place.
It is not completely dead, it still fulfills some functions. I opened it and found some damaged components inside. I have identified the rest but I cannot identify this IC. I don't think I can find the diagram, but can someone help me identify this component?
It seems to be an LDO regulator. I identified it like this:
Pin1 - Vin
Pin2 - GND
Pin3 - ? (connected with pin1)
Pin4 - ADJ ? (resistive divider between Vout and... -
Thanks, but not work
All voltage present, 0.44A consumption and no display....Leave a comment:

Please help to identify this component in red circle. It is a capacitor, but not sure about the type. It is polyester (PET) film? His value seems to be 220nF (224 - hard reading), but also not know the voltage
