These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) The maximum power dissipation which can be safely dissipated for any application is a function of the maximum junction temperature, TJ(MAX) = 125°C, the junction-to-ambient thermal resistance for the SOT-23 package, RθJA = 265°C/W, and the ambient temperature, TA. The maximum allowable power dissipation at any ambient temperature for designs using this device can be calculated using the protection circuitry will protect the device by reducing the output voltage as required to maintain a safe junction temperature. 6.2 ESD Ratings VALUE UNIT V(ESD) Electrostatic discharge Human body model (HBM), per ANSI/ESDA/JEDEC JS-001(1)(2) ±2000 V (1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. (2) The human body model is a 100-pF capacitor discharged through a 1.5-k Ω resistor into each pin.
