These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. The input voltage and output negative-voltage ratings may be exceeded if the input and output current ratings are observed. 2. The output positive-voltage rating may be exceeded up to 4.6 V maximum if the output current rating is observed. 3. The package thermal impedance is calculated in accordance with JESD 51-7. |
