3.3v Switching regulator question.

[Pkmnjunky7]

In short, how many amps does the 3.3 line on the n64 pull? I'm wanting to use this regulator

But I'm afraid of it overheating. I think shockslayer said something about the 3.3 line peaking out at like 1.7, and if this regulator can only handle 1.25, I could be in trouble. I already own said regualtor and have tested it and had no problems, but I haven't played for more than 20 minuntes with it.

Anyone have any suggestions? I know I can use the regulators from TI, but I was just wanting to use this one if possible. I could even buy another one of these regulators and wire the two of them in parallel for more current, but if I do that I'm worried about the voltage level changing...

I used the dimension engineering regulator in my portable however I had to use two in parallel because I was using the expansion pack. From memory using the expansion pack means that the N64 can draw up to 1.5A on the 3.3V line. Without the expansion pack its something like 1.2A. The DESWO33 is only rated for a continuous current of 1A so you'll need another in parallel. Don't worry about the voltage changing. If you look on the product page it explains why parallel works fine.

Thank you very much, I am using the expansion pack, so I will order another and wire them in parallel.
