4 / 23 page LM25115 SNVS418A – NOVEMBER 2005 – REVISED APRIL 2013 www.ti.com These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. ABSOLUTE MAXIMUM RATINGS (1) (2) VBIAS to GND –0.3V to 32V VCC to GND –0.3V to 9V HS to GND –1V to 45V VOUT, CS to GND – 0.3V to 15V All other inputs to GND −0.3V to 7.0V Storage Temperature Range –55°C to +150°C Junction Temperature +150°C ESD Rating HBM (3) 2 kV (1) Absolute Maximum Ratings indicate limits beyond which damage to the component may occur. Operating Ratings are conditions under which operation of the device is specified. Operating Ratings do not imply ensured performance limits. For ensured performance limits and associated test conditions, see the Electrical Characteristics tables. (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 100 pF capacitor discharged through a 1.5k Ω resistor into each pin.
