Notes:

Thermal Resistance (θ_JC)

Notes:

1. Measured on JESD51-7, 4-Layer PCB.

2. The maximum allowable power dissipation is a function of the maximum junction temperature T_{J_MAX}

the junction to ambient thermal resistance θ_JA, and the ambient temperature TA. The maximum allowable

continuous power dissipation at any ambient temperature is calculated by P_{D_MAX}= (T_{J_MAX}-T_A)/θ_JA. Exceeding

the maximum allowable power dissipation will cause excessive die temperature, and the regulator will go into

thermal shutdown. Internal thermal shutdown circuitry protects the device from permanent damage.
