Question about the LM317T

DavGerm4 · Post by **DavGerm4** » Sun Oct 08, 2006 1:58 am

First off, is this just to take place of the DC/DC adapter?

My question is: I couldn't find any 240 Ohms, or 390 Ohms, but I calculated at the website - http://skytroniks.com/317.htm - 560 Ohms as the R1, and 330 Ohms as the R2. The output equals 3.37 V. Is it okay to have this instead of 3.28 V, or would it not work?

Thanks

Also, how do u add pics to ur forum? (like pics that are saved on your computer)
Thanks again...

3.37v is probably safe, but I would measure the output voltage to make sure it's not above 3.4v (massive tolreance).

By the way, that's my site. ^_^

when you say send some, do you mean as in the 240 and 390 Ohms Resistors? If you could that would be great.

sorry for the double post but I have another question about the LM317T. My N64 Fried, and I really don't have money to buy a new one, so I'm just going to do a SNES portable. For building a SNESp, would it need a certain kind of DC/DC converter? If so, couldn't I just use this?

No, SNES requires from 7.2v or more (I say get a 7.2v NiMH battery). Just feed that into the 7805 voltage regulator.

Yes. PM me when you need them.
