3 / 18 page LM3526 www.ti.com SNVS054E – FEBRUARY 2000 – REVISED MARCH 2013 Absolute Maximum Ratings (1) (2) Supply Voltage −0.3V to 6V Output Voltage −0.3V to 6V Voltage at All Other Pins −0.3V to 5.5V Power Dissipation (TA = 25°C) (3) 700 mW TJMAX (3) 150°C (1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Electrical specifications do not apply when operating the device beyond its rated operating conditions. (2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and specifications. (3) The maximum power dissipation must be derated at elevated temperatures and is dictated by TJMAX (Maximum junction temperature), θJA (junction to ambient thermal resistance), and TA (ambient temperature). The maximum allowable power dissipation at any temperature is PDMAX = (TJMAX − TA)/θJA or the number given in the Absolute Maximum Ratings, which ever is lower. θJA = 150°C/W. Operating Ratings Supply Voltage Range 2.7V to 5.5V Operating Ambient Range −40°C to 85°C Operating Junction Temperature Range −40°C to 125°C Storage Temperature Range −65°C to +150°C Lead Temperature (Soldering, 5 seconds) 260°C ESD Rating(1) 2kV ESD Rating Output Only 8kV (1) The human body model is a 100 pF capacitor discharged through a 1.5 k Ω resistor into each pin. Enable pin ESD threshold is 1.7kV. DC Electrical Characteristics Limits in standard typeface are for TJ = 25°C, and limits in boldface type apply over the full operating temperature range. Unless otherwise specified: VIN = 5.0V, VEN = 0V (LM3526-L) or VEN = VIN (LM3526-H).
