Component ID needed

[malc-c]

Hi,

Hoping to help a friend out fixing what seems to be a common issue.

Does anyone have a working Skywatcher wifi dongle who is willing to open the cover and either take closeup decent resolution image of the 6 pin 3.3 volt voltage regulator U1, or can post up the part number.  

TIA

Found this on CN which might help a little to source right or similar component.

OK. Just took mine apart. On mine printed on component U1 is E9=C5P if that helps narrow down the right part.

Oh the joys of SMDs, too small for the true part number to fit so they label them with a unique manufacturers code instead.

Guys thanks for going to all this trouble...  I must admit I half expected Synta not to make things easy and have the actual part number...   I had come across that thread when googling images to see if I could identify the part.  Being a 6 pin device it's not as straight forward as substituting a "normal" three pin linear regulator.   A lot of the pin outs diagrams seems not to follow any standards.

I'll keep searching

Does the Onsemi NCP102 look a likely fit?
You will need to refer to the data and see if the PCB connections look reasonable.
Onsemi don't use this device notation. But a 6 pin TSOP package is not that popular.

HTH, David.

David, thanks for the suggestion.   As for it being a replacement it's really a case of sticking the wet finger in the air and hoping.  Without any clear identification of the original to compare to this is all guesswork.
