4 / 32 page LM317 SLVS044W – SEPTEMBER 1997 – REVISED OCTOBER 2014 www.ti.com 7 Specifications 7.1 Absolute Maximum Ratings over virtual junction temperature range (unless otherwise noted) (1) MIN MAX UNIT VI – VO Input-to-output differential voltage 40 V TJ Operating virtual junction temperature 150 °C Lead temperature 1,6 mm (1/16 in) from case for 10 s 260 °C Tstg Storage temperature range –65 150 °C (1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. 7.2 ESD Ratings MAX UNIT Human body model (HBM), per ANSI/ESDA/JEDEC JS-001, all pins(1) 2500 V(ESD) Electrostatic discharge V Charged device model (CDM), per JEDEC specification JESD22-C101, 1000 all pins(2) (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. 7.3 Recommended Operating Conditions MIN MAX UNIT VO Output voltage 1.25 7 V VI – VO Input-to-output differential voltage 3 40 V IO Output current 1.5 A TJ Operating virtual junction temperature 0 125 °C 7.4 Thermal Information LM317 THERMAL METRIC(1) DCY KCS KTT UNIT 4 PINS 4 PINS 4 PINS RθJA Junction-to-ambient thermal resistance 53 19 25.3 RθJC(top) Junction-to-case (top) thermal resistance 30.6 17 18 °C/W RθJC(bot) Junction-to-case (bottom) thermal resistance — 3 1.94 (1) For more information about traditional and new thermal metrics, see the IC Package Thermal Metrics application report (SPRA953). 4 Submit Documentation Feedback Copyright © 1997–2014, Texas Instruments Incorporated Product Folder Links: LM317 |
