Notes:

1. Exceeding the absolute maximum rating may damage the device.

2. The device is not guaranteed to function outside its operating rating.

3. PD(max) = (TJ(max) – TA) ÷ θJA, where θJA 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. IGND is the quiescent current. IIN = IGND + IOUT.
