<Conditions>
Max. value in change of the output voltage that is caused when changing the output current from 1[mA] to
200[mA] while setting the input voltage to V
Potential difference between input and output voltages when changing the output current as a parameter.
Potential difference between input and output voltages when the output voltage lowers up to 98[%] by
reducing the input voltage by degrees while maintaining the output current.
<Conditions>
Specify input-output potential differences Typ. and Max., using output current I
reference.
