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 and output voltage ratings may be exceeded if the input and output current ratings are observed. 2. This value is limited to 7 V maximum. 3. The maximum package power dissipation is calculated using a junction temperature of 150 °C and a board trace length of 750 mils. |
