Notes:
1. Exceeding an absolute maximum rating may damage the device.
2. The device is not guaranteed to function outside its operating rating.
3. The maximum allowable power dissipation at any T_A (ambient temperature) is P_D(max) = (T_J(max) – T_A) / θ_JA. Exceeding the maximum allowable power
dissipation results in excessive die temperature, and causes the regulator to enter thermal shutdown.
4. Devices are ESD sensitive; use proper handling precautions.
5. Specifications are for packaged products only.
6. Line regulation is a percentage of V_OUT.
