Application Note
Maximum Power Dissipation Calculation:
PD (max) =［ ( VIN (max) – VO (nom) ) ］x IO (nom) + VIN (max) x IQ
Where: VO(nom) : The nominal output voltage
IO(nom): The nominal output current and
IQ: The quiescent current the regulator consumes at IO(MAX)
VIN(max): The maximum input voltage
