Hi there,
I'm calculating the thermal characteristics of LMT87QDCKTQ1 and found the equation below in the datasheet (page 11):
Tj = Ta + Tja.[(Vdd.Is) + (Vdd - Vout ).IL]
In the same page below the equation, there's an example where the parameters are: Ta = 30°C, Vdd = 5 V, Is = 5.4 μA, Vout = 2231 mV, and IL= 2 μA.
Then the result for the junction temperature in the given example is 30.014°C. Which thermal resistance junction to ambient is being used to achieve this value?
Ps.: In page 6 of the datasheet, the values for Rth,j-a are 275 °C/W (5 pins) and 167 °C/W (3 pins) but both don't match the mentioned result if applied to the used example.
