But actually, looking more closely at the datasheet requirement, the ripple requirement is specified from 10 kHz to 80 MHz. And this switching noise is much higher frequency (presumably within the range that substrate bypass caps would notch most of it out).
With a FIR LPF applied to the measured waveform to cut off everything past 80 MHz, I'm only seeing about 2 mV of ripple.
