The device is specified from –40 °C to 125 °C for a voltage rating of 2.5 V to 38 V. Because the part is draining at its maximum a current of 17 mA the maximum voltage that can be applied will depend on what is the maximum ambient temperature acceptable for the application. The curve in Figure 8-23 shows the maximum acceptable power supply voltage versus the maximum acceptable ambient temperature.

The Figure 8-23 can also be calculated using the following formulas:

Equation 1.

where

- T
_{J}is the junction temperature - T
_{A}is the ambient temperature - ΔT is the difference between the junction temperature and the ambient temperature

Equation 2.

where

- P
_{D}is the power dissipated by the part - R
_{θJA}is the junction to ambiant thermal resistance

Equation 3.

where

- V
_{CC}is the voltage supply of the device - I
_{CC}is the current consumption of the device

Combining the three equations above gives Equation 4 below:

Equation 4.

This equation gives the maximum voltage the part can handle in regards of the ambient temperature.

For example, in the
application required to work within a ambient temperature of maximum 85 °C, with
T_{Jmax}, R_{θJA} and I_{CCmax} are defined in the data sheet, the
maximum voltage allowed for this application is determined in Equation 5:
