www.ti.com 6 Specifications 6.1 Absolute Maximum Ratings
over operating free-air temperature range (unless otherwise noted)(1)
MIN MAX UNIT
Maximum Input Voltage (VIN to GND) 20 V Power Dissipation(2) Internally Limited Junction Temperature (TJ)(2) 150 °C TO-220 (T) Package, 10 s 260 Lead Temperature °C SOT-223 (MP) Package, 4 s 260 Storage Temperature, Tstg –65 150 °C (1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) The maximum power dissipation is a function of TJ(max) , RθJA, and TA. The maximum allowable power dissipation at any ambient temperature is PD = (TJ(max)–TA)/RθJA. All numbers apply for packages soldered directly into a PCB.
6.2 ESD Ratings VALUE UNIT
V(ESD) Electrostatic discharge Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) ±2000 V (1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. Pins listed as ±2000 V may actually have higher performance.
6.3 Recommended Operating Conditions
over operating free-air temperature range (unless otherwise noted)
MIN MAX UNIT
Input Voltage (VIN to GND) 15 V LM1117 0 125 °C Junction Temperature (TJ)(1) LM1117I −40 125 (1) The maximum power dissipation is a function of TJ(max) , RθJA, and TA. The maximum allowable power dissipation at any ambient temperature is PD = (TJ(max)–TA)/RθJA. All numbers apply for packages soldered directly into a PCB.
