(VIN2 + 0.3 V) Storage Temperature Range −65°C to +150°C Operating Junction Temperature Range −40°C to +125°C Soldering Conditions JEDEC J-STD-020 Stresses at or above those listed under Absolute Maximum Ratings may cause permanent damage to the product. This is a stress rating only; functional operation of the product at these or any other conditions above those indicated in the operational section of this specification is not implied. Operation beyond the maximum operating conditions for extended periods may affect product reliability.
