Note :

1. Exceeding the maximum allowable power disspation will result in excessive die temperature, and the regulator will go into

thermal shutdown.

2.TJ: Junction Temperature Calculation:

T_J= T_A+ (P_D× θ_JA)

The θ_JAnumbers are guidelines for the thermal performance of the device/PC-board system. All of the above assume no

ambient airflow.

3.θ_JA:Thermal Resistance-Junction to Ambient, D_F: Derating factor, Po: Power consumption.

4.θ_JT:Thermal Resistance-Junction to Ambient, T_C: case(Tab) temperature,

T_J= T_C+ (P_D× θ_JT)

for S package.
