Does this step down regulator look like it would work?

Thanks

Nope, it can only output up to .5A. The 3.3v line requires about 1.5A. This one would work, but there are much cheaper solutions.

or you could get them for free from TI

The deswadj (supplying up to 1.2A) on the same site works for a 3.3V line on a N64 with a jumper pack. I used two of these within my portable because I used an expansion pack and also because I wanted to stay within operating limits. It is rated at 1A but can do 1.2A fairly constantly.

Despite this I would recommend using a TI regulator or making your own using something like an LM317T. Its cheaper and supply as much power as you need it you use the right regulators. I've found how easy it is to make your own. Give it a try, use some veroboard and ramp up your cred in the process.

1amp is fine for a jumper pak, up to 1.5amps needed (max) for expansion pack as I recall. On the same site there is a regulator that works 3v+ at 3amps which is fine, at a small extra price. If you can't get a TI card, this might be a good option.

Can someone link me to the TI switching regulator?

Yeah... I meant for the TI switching regulator.

EDIT: never mind
