Note 1: The Thermal Resistance specifications are based on a JEDEC standard JESD51-3 single-layer PCB. θJA will vary with

board size and copper area.

Note 2: The maximum allowable power dissipation is a function of the maximum junction temperature, TJ-MAX, the

junction-to-ambient thermal resistance,θJA, and the ambient temperature, TA. The maximum allowable power dissipation at any

ambient temperature is calculated using: PD(MAX) = (TD(MAX) - TA)/θJA. The maximum power dissipation is determined using TA=

25℃, and TJ(MAX)= 125℃
