At nominal input and output voltage and maximum load.
Total error band is defined as the static output regulation at 25°C including
initial setting accuracy, input voltage within stated limits and output
current within stated limit.
Output can be externally trimmed
by using either method shown below.

4
Measured with 10µF tantalum capacitor across output.
EMI measured on either line into a 50Ω LISN with 120µF electrolytic input
capacitor.

Overvoltage limit may be tested by applying -5V to -15V to the trim pin 11
with respect to –sense pin 18.
To order optional standard heatsink, please add suffix ‘-1’ to model
number e.g. BXA75-48S05-1.
