psone power options

**jesse123** · 11-20-2005, 03:44 PM

I have a psone screen and would like to power it from my car battery, I was originally planning on getting a psone car adapter and just using that; however, I can't find one in any store around me. Mouser has 7.5volt regulator ICs that are $0.73, I was wondering if I could use one of these to save me some money. Would one of these work to power the psone from a car battery? If so, would the regualtor chip be the only thing I need? Also, these IC's put out 2A, would this be enough to power the screen?

Here are the specs:
Mouser Part #: 511-L78S75CV
Mfr. Part #: L78S75CV
TO-220AB 7.5v 2.0a

Thanks,
Jesse

Anyone? Or should this go in the power supply section? I put it here because it is the first thing I'd like to straighten out before I start buying parts.

Posting here is good.

Did you check the current projects for PSone screen in the forum to see what other people is doing?

What is the current need it for the screen?

Yea I've looked through the forums, seems like everyone is using the car adapter.
The screen uses 7.5 volts.

I'm talking about Amperes.

Well the ac adapter for the psone screen and console has an output of 3A. Would the lcd actually draw 3A?

**thanatos106** · 11-21-2005, 07:41 PM

Well that is what i'm trying to figure out.

Cus if you put that regulator and the current is about of it, the screen will (or not at all) work with problems (diming the image, powering off etc)

Thanks, I wonder if this means that the psone screen could be powered the same way but with a 7.5 volt regulator? Has anyone tried this sort of thing with the psone lcd?

So if I found a regulator ic that put out 7.5 volts with 3A instead of 2A, would it work?
