Look around on TI for an adjustable regulator!

I'm pretty sure that a 7805 is designed to output one amp, but I have no idea how much amperage a ps2 needs. But, shockslayer ir right, a ti card would work a lot better.

OK, New Formula:

PS2 Slim + 12V + 7805 + 220 Ohm Resistor + 470 Ohm Resistor + Heatsink = Yay?

EDIT: So I built the circuit and the PS2 booted up to main menu. YAY! When I insert a disc, it turns off to standby! Awww...

And I have to use a bigger heatsink. The HS I'm using was HOT!


7805 cant handle the amps. Use two in parallel or go with a different solution

7805's don't work for crap in parallel. Try an LM117 if you have an in-case air conditioner (cause those things will get hot enough to melt through your case)

You really, really, need a switching regulator for this one. No two ways about it.

The formula WORKS!

PS2 Slim + 12V + (7805 x 2) + 220 Ohm Resistor + 470 Ohm Resistor + Heatsink = Yay!!!

Click on the thumbnails to open them. It seems ImageShack is not loading my pics now so I have to host them to somewhere else.
