Load regulation is within 1% on all primary rails. I would like to see a tighter load regulation at 12V, given the digital control.

A glance at the light-load table is always useful, as the PSU typically operates at light loads.
Ripple Suppression
Ripple in power supplies refers to the small, unwanted AC voltage fluctuations superimposed on the DC output. It occurs due to imperfect filtering during the AC-to-DC conversion. Lower ripple is highly preferable because it ensures a cleaner, more stable DC output, reducing noise and potential interference in sensitive electronics, improving performance, and extending component lifespan. High ripple can cause instability, overheating, or damage to connected devices.
