5 / 29 page LP3985 www.ti.com SNVS087AC – OCTOBER 2000 – REVISED MAY 2013 Absolute Maximum Ratings (1) (2) (3) VIN, VEN −0.3 to 6.5V VOUT −0.3 to (VIN+0.3) ≤ 6.5V Junction Temperature 150°C Storage Temperature −65°C to +150°C Lead Temp. 235°C Pad Temp.(4) 235°C Maximum Power Dissipation SOT23-5(5) 364mW DSBGA(5) 314mW ESD Rating(6) Human Body Model 2kV Machine Model 150V (1) Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which operation of the device is verified. Operating Ratings do not imply verified performance limits. For verified performance limits and associated test conditions, see the Electrical Characteristics tables. (2) All voltages are with respect to the potential at the GND pin. (3) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and specifications. (4) Additional information on lead temperature and pad temperature can be found in Texas Instruments Application Note AN- 1112(SNOA401). (5) The Absolute Maximum power dissipation depends on the ambient temperature and can be calculated using the formula: PD = (TJ - TA)/θJA,where TJ is the junction temperature, TA is the ambient temperature, and θ JA is the junction-to-ambient thermal resistance. The 364mW rating for SOT23-5 appearing under Absolute Maximum Ratings results from substituting the Absolute Maximum junction temperature, 150°C, for TJ, 70°C for TA, and 220°C/W for θJA. More power can be dissipated safely at ambient temperatures below 70°C . Less power can be dissipated safely at ambient temperatures above 70°C. The Absolute Maximum power dissipation can be increased by 4.5mW for each degree below 70°C, and it must be derated by 4.5mW for each degree above 70°C. (6) The human body model is 100pF discharged through 1.5k Ω resistor into each pin. The machine model is a 200 pF capacitor discharged directly into each pin. Operating Ratings (1) (2) VIN 2.5 to 6V VEN 0 to (VIN+0.3) ≤ 6V Junction Temperature −40°C to +125°C Thermal Resistance θJA (SOT23-5) 220°C/W θJA (DSBGA) 255°C/W Maximum Power Dissipation SOT23-5(3) 250mW DSBGA(3) 216mW (1) Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which operation of the device is verified. Operating Ratings do not imply verified performance limits. For verified performance limits and associated test conditions, see the Electrical Characteristics tables. (2) All voltages are with respect to the potential at the GND pin. (3) Like the Absolute Maximum power dissipation, the maximum power dissipation for operation depends on the ambient temperature. The 250mW rating for SOT23-5 appearing under Operating Ratings results from substituting the maximum junction temperature for operation, 125°C, for TJ, 70°C for TA, and 220°C/W for θJA into PD = (TJ - TA)/θJA from above. More power can be dissipated at ambient temperatures below 70°C . Less power can be dissipated at ambient temperatures above 70°C. The maximum power dissipation for operation can be increased by 4.5mW for each degree below 70°C, and it must be derated by 4.5mW for each degree above 70°C.
