voltage
(1) Line and load regulation is measured as a percentage deviation from the nominal value (i.e., as percentage deviation from the nominal
output voltage). For line regulation, x %/V stands for ± x% change of the nominal output voltage per 1-V change on the input/supply
voltage. For load regulation, y% stands for ± y% change of the nominal output voltage per the specified current change.
(2) For proper operation the voltage at LBI may not exceed the voltage at V
