Load Regulation
Load regulation is the regulation of output voltage changes in the event of load fluctuations. Especially in dynamic areas, the quality of a switched-mode power supply becomes apparent when it is necessary to keep the output voltage as constant as possible even during violent changes in the output current. Especially with very small loads or with minimum input voltage and full load, very strong overshoots or even dips can occur in extreme cases, which may even lead to malfunctions or damage. Load regulation should be within 1% for 12 V, as well as for the slave rails (5 V and 3.3 V).
Ripple Suppression
Ripple suppression is good on all rails.
Transient Response
Transient response is the amount of deviation in the output voltage as a result of a change in load. If the load changes, the power supply cannot immediately adjust to the new conditions and therefore either delivers too much or too little stored energy. Transient response is good enough at 12 V, but could be better on the secondary rails.
