The accuracy of the output voltage is ± 2.0% guaranteed under the specified conditions for input voltage,
which differs depending upon the product items, output current, and temperature.
Indicate the input voltage dependencies of output voltage. That is, the values show how much the output
voltage changes due to a change in the input voltage with the output current remained unchanged.
