[sdiy] Precision power regulators for low noise circuits?

[Grant Richter]

Adjustable regulators LM317 and LM337 have improved specs over fixed  
voltage types.

The industry standard is uA723 or equiv. which has specs about 10  
times better than LM7815/7915.

Virtually every commercial linear power supply is going to have  
uA723s in it. Or they build the same circuit discretely.

Switching supplies are usually avoided for low noise designs, I am  
sure there are exceptions.

Some regulars use a switcher followed by a linear stage for  
efficiency and low noise, they are expensive.
