Measured across one 1.0 uF ceramic
capacitor and a 10uF tantalum capacitor –
see input/output ripple measurement figure;
BW = 20MHz
Output Voltage Adjustment Range 90 --- 110 %Vo,nom
The trim range is reduced to 105% when
the input voltage is below 40V.
Output Voltage Sense Range --- --- 10 %Vo,nom
The sense range is reduced to 5% when the
input voltage is below 40V.
