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 TA (ambient temperature) is PD(max) = (TJ(max) – TA) / θJA. 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. Human body model, 1.5k Ω in series with 100pF. 5. Specifications are for packaged products only. |
