Attention: RC-CAM.com will be closing down August 2021.

The RC-Cam.com forum was the very first online community dedicated to the advancement of wireless video cameras on radio controlled (R/C) models. This is now called "FPV" (First Person View). We are proud of the contributions that our members have made to the FPV hobby.

We've seen significant changes over the last twenty years. Initially there were a lot of eager R/C hobbyist that built their own video systems. Allowing these creative individuals to share their work was the purpose of this site. Now the FPV market is flooded with low cost systems; Sadly DiY FPV video projects are now rarely discussed.

RC-CAM.com (main site and forum) will be closing down August 2021. This is being announced now (March 2021) so that everyone has time to download any information that is important to them. After the site is shutdown the information will no longer be available here.

We appreciate every member's involvement with advancing the FPV hobby. It is indeed sad to say goodbye to all our online friends. Be safe and stay healthy.

Help finding SMT voltage regulator

Recommended Posts

So about a year ago I bought a VSN505 camera, knowingly ordering the 5 volt version as it isn't as noisy as the 12 volt one. I didn't install it in anything until

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

this regulator?

Here is the link to the Digikey page:

Seiko Vregs are difficult to buy and the HSON-6 pkg makes it even more troublesome.

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.

Thanks for the reply and ideas. What about finding another product with a Seiko vreg in it I could steal? Any ideas?
