[sdiy] LDO regulators

[Paul Higgins]

Hi all,

I was wondering if anyone has some advice on low-dropout voltage 
regulators.  Is there a line that roughly corresponds with the old 
78xx/79xx series?  I've looked through my Mouser and Digi-Key catalogs 
and I'm surprised at the baffling number and variety of LDO regulators 
out there.

The regulator should be available in TO-220 or TO-3 form (or similar 
through-hole part) if possible.  I need current of up to say 1-1.5 A or 
so; of course it would be great to know about any 323/338/350-style 
high current regulators as well, especially those that have adjustable 
voltage.

Thanks,
-PRH
