Different 3.3v regulator?

Different 3.3v regulator?

Post by bacteria »

Life of Brian showed the 5v step down regulator he used on his wonderful SNES portable; looking on the site I see they have a 3.3v one, 1 amp.

Would I be right in saying this one may be better than the TI alternative (no resistor needed); would it be suitable and stable, for the N64 given the juice it needs to run?

I don't believe that a one-amp regulator is strong enough to handle the current of the N64. The LD1585C series from ST provides up to 5A output current, check into the LD1585C-3.3. For future references, Digikey is your buddy!

However I don't understand your dislike of the TI converter - it's just a resistor...

Skyone - Thanks for the reply, mate. I don't have a dislike for the TI, I don't have a view as such either way (it's either good or not), I just wanted someone to confirm that it is reliable under load and doesn't spike or peak, to date I haven't had such reassurances, which is why when I finish my project I intend to rig a bare-bones N64 system up and leave it running for a while to see if all is ok or not. It isn't a lack of faith in the TI board, it is a lack of faith in my electronics skills as I can copycat what I need to do (as I have done) but have no way to know if it is ok without testing. This is especially relevant as I only have one TI board and I experimented with it with various resistors I had ages ago, before I understood what I had to do (duh!), and I therefore have no idea if I damaged it or not in the process :roll: Perhaps this clarifies!

What I am really after is a unit which works out of the box (removes this issue), no additional components required (as with the TI), just solder your power cables in and out and off you go; that is why I wondered about the unit mentioned, it seems to conform to this criteria.

BTW - the car adapter I use at the moment is 1 amp output, on the few games I have tested on my portable, it works fine. I would ideally like to change the car adapter though, so I can use an Expansion Pack instead of the Jumper Pak; and have the option for batteries in the future if I want to add them.
