6. Temperature coefficient of output voltage
The shadowed area in Figure 13 is the range where V
when the temperature coefficient of the output voltage is ±100 ppm/°C.
A change in the temperature of the output voltage [mV/°C] is calculated using the following equation.
*1. Change in temperature of output voltage
*2. Specified output voltage
*3. Output voltage temperature coefficient
