Default Super Regulator

I would like to build a series of voltage regulators (5v,9v,12,15v) or a variable regulator that works well. I want to build a low current (~100mA) version and a high current (1.5A) version of each voltage. My goal is to build the best regulator(s) possible.

But I am confused though on what are factors of a voltage regulator are important. And within those factors which are more important than others.

I keep reading posts where people talk about the following;

Line Regulation
Load Regulation
Ripple Rejection
Noise

I have learned what each are but don't know if any are more important than others.

Are there any other factors I should be considering?

At first these regulator(s) will just be for general purpose. But later I will build a couple AM transmitters / radios and would like clean/stable dc for the oscillators. I also in vision adding a regulated power supply to my gain clone amp.

Hopefully not getting ahead of myself but I have been favoring the ua725 and LT1086. I have seen a few discrete regulator here but they don't have any specs. So I don't know how to compare them to IC. Any recommendation on designs or ICs?

Thank,
Matt

go to Walt Jung's site and read up his articles on regulators, noise, CCS etc.

Have a look on here at the TeddyReg and PowerReg threads. There has just been a group buy of the pcb's and parts required.
