Notes:
1. Exceeding maximum ratings may damage the device.
2. The device is not guaranteed to work outside its operating ratings.
3. The maximum allowable power dissipation of any T_A (ambient temperature) is P_D(max) = (T_J(max) – T_A) ÷ θ_JA. Exceeding the maximum allowable
power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown.
4. Specification for packaged product only.
