4 / 20 page LM3480 SNVS011H – JUNE 1999 – REVISED SEPTEMBER 2015 www.ti.com 6 Specifications 6.1 Absolute Maximum Ratings (1) (2) MIN MAX UNIT Input voltage (IN to GND) –0.3 35 V Power dissipation(3) Internally Limited Junction temperature(3) –40 150 °C Storage temperature, Tstg −65 150 °C (1) Absolute Maximum Ratings are limits beyond which damage to the device may occur. Recommended Operating Conditions are conditions under which operation of the device is ensured. Recommended operating ratings do not imply ensured performance limits. For ensured performance limits and associated test conditions, see the Electrical Characteristics: LM3480-3.3, LM3480-5. (2) If Military- or Aerospace-specified devices are required, please contact the TI Sales Office/Distributors for availability and specifications. (3) The Absolute Maximum power dissipation depends on the ambient temperature and can be calculated using P = (TJ – TA) / RθJA where TJ is the junction temperature, TA is the ambient temperature, and RθJA is the junction-to-ambient thermal resistance. The 370-mW rating results from substituting the Absolute Maximum junction temperature, 150°C for TJ, 50°C for TA, and 269.6°C/W for RθJA. More power can be safely dissipated at lower ambient temperatures. Less power can be safely dissipated at higher ambient temperatures. The Absolute Maximum power dissipation can be increased by 3.7 mW for each °C below 50°C ambient. It must be derated by 3.7 mW for each °C above 50°C ambient. Heat sinking enables the safe dissipation of more power. The LM3480 actively limits its junction temperature to about 150°C. 6.2 ESD Ratings VALUE UNIT Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) ±2000 Electrostatic V(ESD) V discharge Charged-device model (CDM), per JEDEC specification JESD22-C101(2) ±500 (1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. (2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process. 6.3 Recommended Operating Conditions over operating free-air temperature range (unless otherwise noted) (1) MIN MAX UNIT Maximum input voltage (IN to GND) 0 30 V Junction temperature (TJ) –40 125 °C (1) Absolute Maximum Ratings are limits beyond which damage to the device may occur. Recommended Operating Conditions are conditions under which operation of the device is ensured. Recommended operating ratings do not imply ensured performance limits. For ensured performance limits and associated test conditions, see the Electrical Characteristics: LM3480-3.3, LM3480-5. 6.4 Thermal Information LM3480 THERMAL METRIC(1) SOT-23 (DBZ) UNIT 3 PINS RθJA Junction-to-ambient thermal resistance 269.6 RθJC(top) Junction-to-case (top) thermal resistance 141.1 RθJB Junction-to-board thermal resistance 63.1 °C/W ψJT Junction-to-top characterization parameter 24.2 ψJB Junction-to-board characterization parameter 62.1 (1) For more information about traditional and new thermal metrics, see the IC Package Thermal Metrics application report, SPRA953. 4 Submit Documentation Feedback Copyright © 1999–2015, Texas Instruments Incorporated Product Folder Links: LM3480 |
