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

*1. The maximum deviation of the actual measurement of output voltage (B) and an approximation line (A) in
temperature within −20°C to 80°C. The approximation line is the line drawn so that “a” should be the minimum
value.
*2. The difference of the output voltage within −20°C to 80°C.

4. Line regulation (∆V_OUT1)
∆V_OUT1 indicates the output voltage dependency of 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 (∆V_OUT2)
∆V_OUT2 indicates the output voltage dependency of 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.
