Load Regulation
Load regulation is the regulation of output voltage changes in the event of load fluctuations. The quality of a switched-mode power supply is particularly evident in dynamic areas when it comes to keeping the output voltage as constant as possible even during sharp changes in the output current. Particularly with very small loads or at minimum input voltage and full load, very strong overshoots or even dips can occur in extreme cases, which can even lead to malfunctions or damage under certain circumstances. The load regulation should be within 1 % at 12 V, as well as with the auxiliary rails (5 V and 3.3 V), and it is.
