These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
ELECTRICAL CHARACTERISTICS

Note 1:
All devices are 100% production tested at TA = +25°C. All temperature limits are guaranteed by design.
Note 2:
Output resistance is guaranteed with capacitor ESR of 0.3Ω or less.
