Help finding SMT voltage regulator
Posted 25 January 2011 - 02:27 PM
recently, and up to this point all of my video transmitters and cameras have been 12 volt systems. To make a long story short, I stupidly forgot my VSN505 was a 5 volt
camera and just hooked it into one of my 12 volt wire harnesses. Sooo, I found only one visible burned part on the board, which is a 3.7 volt LDO voltage regulator.
Manufactor part number is S-1131B37PD-N4WTFG. It is available at digikey, but only in orders of 3000 or more. Obviously not an option. Anybody know where I can find
Here is the link to the Digikey page:

This one is close, but the pin-out is wrong:
If you run out of ideas then perhaps you can improvise and use a 3.3V LDO device in different package. With some effort, you could dead-bug it onto the board.

I think that you will find that to be a needle-in-a-haystack effort.
What about finding another product with a Seiko vreg in it I could steal?
