The shadowed area in Figure 12 is the range where VOUT varies in the operating temperature range

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.

[ ] [ ] [ ] ∆VOUT mV/°C *1 = VOUT(S) V *2 × ∆VOUT ppm/°C *3 ÷ 1000
