6. Temperature coefficient of output voltage
Load regulation indicates the output current dependence of output voltage. The value shows how much
the output voltage changes due to the change of the output current when the input voltage is kept
constant.
Let V
(V
and the resultant output voltage defined as following equation.

The output voltage lies in the shaded area in the whole operating temperature shown in Figure 11 when
the temperature coefficient of the output voltage is ± 100 ppm/ ° C.
*1. The value of the output voltage measured at 25 ° C.
Temperature change ratio for output voltage [mV/°C] is calculated by using the following equation.
