Hmmmm I wasn't impressed. The 'scope screen shot of noise levels on the outputs used 20mV/division, and the thickness of the regulated traces told us precisely nothing. Now if the author had measured 20uV noise over a BW of 10Hz to 100kHz (about 63nV/rtHz), or 3uV over the same BW (about 10nV/rtHz), I'd have started to get interested.
However as no claims were made, I took the title of "Ultra-Low Noise" with a large shovel of salt.

It is a combination of switcher and LDO's and written by P Hunter TI so it may also be available on their site.
