3. Nonlinearity (∆N_L)
∆N_L is the nonlinearity of output voltage. Its deviation with the approximation line is shown below.
∆N_L is calculated from the following formula.

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

4. Line regulation (∆V_OUT1)
∆V_OUT1 indicates the dependency of output voltage against input voltage. This indicates how much the output voltage
varies when changing the input voltage after fixing the output current constant.
5. Load regulation (∆V_OUT2)
∆V_OUT2 indicates the dependency of output voltage against output current. This indicates how much the output voltage
varies when changing output current after fixing the input voltage constant.
6. Current consumption – Power supply voltage (∆I_DD1)
∆I_DD1 indicates the dependency of current consumption against power supply voltage. This indicates how much current
consumption varies when changing the temperature after fixing an output current constant.
7. Current consumption － Temperature (∆I_DD2)
∆I_DD2 indicates the dependency of current consumption against temperature. This indicates how much current
consumption varies when changing the temperature after fixing an output current constant.
