gone a while, any new regulated PSU designs?

Aghead · 5th May 2007, 04:32 PM

I'm looking to build a new regulated PSU since I was so impressed with Carlosfm's LM338 design, the best thing I've heard since bypassing the preamp...

But it looks like he has been snubbed, too bad.

Does anyone have a newer competing design or is Carlos' still the reference?

There are lots of ways to make a regulated supply. Have a look through the power supply forum. Carlosfm's design really wasn't anything special.

Try different chips instead of the LM338.

try LT10** series chip.

Lol: LM7*xx

*= 8 for +, 9 for -.
XX= 05 through 24 in certain increments.

PS: This is an OLD regulator though, so you probably have heard of it.

Why do you need a competing design? If you like the result, use it. There really isn't anything to want beyond it, the noise level is sufficiently low to work well with typical chipamp chips and it is a basic, inexpensive and easy to build circuit. Is it TOO easy, you want a challenge? I suppose you could put a capacitance multiplier in front of it and add pass transistors for higher current, or sort of incorporate the two into the same stage.
