APPLICATION NOTE:
1. Maximum Power Dissipation Calculation:
PD(max) = [(VIN(max) - VO(nom))] × IO(nom) + VIN(max) × IQ
Where: VO(nom) : The nominal output voltage
I
O(nom) : The nominal output current, and
IQ : The quiescent current the regulator consumes at IO(MAX)
IN(max) : The maximum input voltage
Then θJA = (150OC – TA) / PD
V
