The shadowed area in Figure 11 is the range where VOUT varies in the operating temperature range
when the temperature coefficient of the output voltage is ±100 ppm/°C.

*1. VOUT(E) is the value of the output voltage measured at 25°C.
Figure 11
A change in the temperature of the output voltage [mV/°C] is calculated using the following equation.
ΔVOUT [mV / °C]*1 = [ VOUT(S) V]*2 × ΔVOUT [ppm / °C]*3 ÷1000
