PRODUCTION DATA.
Calculate power dissipated in the device using Equation 4.
space
where:
PD = continuous power dissipation
IO = output current
VIN = input voltage
VOUT = output voltage
As I(q) << IO, therefore ignore the term I(q) × VIN in Equation 4.
For a device under operation at a given ambient air temperature (TA), calculate the junction temperature (TJ) using Equation 5.
space
where:
RθJA = junction-to-ambient air thermal impedance
