Looking for 300-350 ma regulator

[poguy]

I'd like to do a project with some 1 watt LED's and need a constant-current
regulator good for 12 volt input. Something like this:

only with 300-350 ma out instead of 700 ma.

Any ideas? Everything I've seen for 300-350 ma is made for fairly low input
voltages.

Thanks!

That looks good, thanks.

You could buy the kaidomain regulator, and just change the current-sense resistor.
The Kaidomain regulator uses a PT4105 http://www.micro-bridge.com/data/CRpowtech/PT4105E.pdf with a R270 resistor to give ~700mA output.

Now that kicks butt. I can pick up the surface mount resistors cheap locally
and keep the cost low.

Thanks!
