3. Nonlinearity (ΔN_L)
ΔN_L indicates the nonlinearity of the output voltage and is defined as the difference of the characteristic curve of
the output voltage and the approximated straight line shown below.
ΔN_L is calculated using the following formula.

*1. The maximum deviation of the actual measurement of output voltage (B) and an approximated straight
line (A) in temperature within −20 °C to 80 °C. (An approximated straight line is taken as the straight line
from which the “a” becomes the minimum.)
*2. The difference of the output voltage within −20 °C to 80 °C.
4. Line Regulation (ΔV_OUT1)
ΔV_OUT1 indicates the output voltage dependence on the input voltage. That is, the values express how the
output voltage changes, when input voltage is changed under the condition that output current is fixed.
5. Load regulation (ΔV_OUT2)
ΔV_OUT2 indicates the output voltage dependence on the output current. That is, the values express how the
output voltage changes, when output current is changed under the condition that input voltage is fixed.
