Notes:
1. Exceeding the absolute maximum rating may damage the device.
2. The device is not guaranteed to function outside its operating rating.
3. P_D(max) = (T_J(max) – T_A) ÷ θ_JA, where θ_JA depends upon the printed circuit layout, see “Applications Information.”
4. Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k in series with 100pF.
5. Specification for packaged product only.
6. I_GND is the quiescent current. I_IN = I_GND + I_OUT.
