4 / 27 page Absolute Maximum Ratings (Note 1) If Military/Aerospace specified devices are required, please contact the National Semiconductor Sales Office/ Distributors for availability and specifications. VIN -0.5V to 7V FB Voltage -0.5V to 3V EN Voltage -0.5V to 7V SW Voltage -0.5V to 7V ESD Susceptibility 2kV Junction Temperature (Note 2) 150˚C Storage Temperature −65˚C to +150˚C Soldering Information Infrared or Convection Reflow (15 sec) 220˚C Operating Ratings VIN 3V to 5.5V Junction Temperature −40˚C to +125˚C Electrical Characteristics VIN = 5V unless otherwise indicated under the Conditions column. Limits in standard type are for T J = 25˚C only; limits in boldface type apply over the junction temperature (TJ) range of -40˚C to +125˚C. Minimum and Maximum limits are guaranteed through test, design, or statistical correlation. Typical values represent the most likely parametric norm at T J = 25˚C, and are provided for reference purposes only.
