3 / 32 page LM2727, LM2737 www.ti.com SNVS205D – AUGUST 2002 – REVISED MARCH 2013 Absolute Maximum Ratings (1) (2) VCC 7V BOOTV 21V Junction Temperature 150°C Storage Temperature −65°C to 150°C Soldering Information Lead Temperature (soldering, 10sec) 260°C Infrared or Convection (20sec) 235°C ESD Rating(3) 2 kV (1) Absolute maximum ratings indicate limits beyond which damage to the device may occur. Operating ratings indicate conditions for which the device operates correctly. Opearting Ratings do not imply ensured performance limits. (2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and specifications. (3) The human body model is a 100pF capacitor discharged through a 1.5k resistor into each pin. Operating Ratings Supply Voltage (VCC) 4.5V to 5.5V Junction Temperature Range −40°C to +125°C Thermal Resistance ( θJA) 155°C/W Electrical Characteristics VCC = 5V unless otherwise indicated. Typicals and limits appearing in plain type apply for TA=TJ=+25°C. Limits appearing in boldface type apply over full Operating Temperature Range. Datasheet min/max specification limits are ensured by design, test, or statistical analysis.
