For packages with exposed thermal pads, such as QFN, PowerPAD, and PowerFLEX,
θ
JP is defined as the thermal resistance between the die
junction and the bottom of the exposed pad.
NOTE 1: Maximum power dissipation is a function of TJ(max),
θ
JA, and TA. The maximum allowable power dissipation at any allowable ambient
temperature is PD = (TJ(max) TA)/
θ
JA. Operating at the absolute maximum TJ of 150
°
C can affect reliability.

The input-to-output differential across the regulator should provide for some margin against regulator operation at the maximum dropout (for a
particular current value). This margin is needed to account for tolerances in both the input voltage (lower limit) and the output voltage (upper limit).
The absolute minimum VIN for a desired maximum output current can be calculated by the following:
VIN(min) = VOUT(max) + VDO(max @ rated current)
