Notes:
1. „Total Regulation“ is the output voltage tolerance which includes
initial voltage accuracy, thermal drift, line regulation and load regu-
lation at rated input voltage and load condition.
2. „Ripple & Noise“ is maximum peak-to-peak voltage value mea-
sured at output within 20MHz bandwidth at rated line voltage and
output load ranges, and with a 47 µF low-ESR electrolytic capaci-
tor in parallel with a 0.1 µF ceramic capacitor across the output.
