Load regulation is only tight enough on the minor rails, but I would like to see within 1% at 12V.

50% Load 14.3 mV 9.3 mV 9.9 mV 6.9 mV Pass
60% Load 13.2 mV 9.7 mV 9.3 mV 7.2 mV Pass
70% Load 12.3 mV 8.8 mV 8.3 mV 8.1 mV Pass
80% Load 15.1 mV 9.3 mV 9.6 mV 9.0 mV Pass
90% Load 16.9 mV 9.7 mV 9.8 mV 9.5 mV Pass
100% Load 20.3 mV 12.3 mV 13.4 mV 13.4 mV Pass
110% Load 24.9 mV 12.9 mV 14.7 mV 13.6 mV Pass
Crossload 1 6.1 mV 10.7 mV 10.4 mV 6.9 mV Pass
Crossload 2 6.2 mV 12.2 mV 6.8 mV 6.3 mV Pass
Crossload 3 6.7 mV 9.8 mV 11.1 mV 6.4 mV Pass
Crossload 4 18.2 mV 10.2 mV 11.2 mV 11.6 mV Pass

Ripple suppression is good on all rails.
