The shadowed area in Figure 12 is the range where V_OUT 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
