6 Specifications

6.1 Absolute Maximum Ratings

over operating free-air temperature range (unless otherwise noted)(1)
MIN MAX UNIT
Continuous input voltage, VI 16 V
Operating virtual junction temperature, TJ 150 °C
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.

6.2 ESD Ratings

VALUE UNIT
V(ESD) Electrostatic discharge Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) 2000 V
Charged-device model (CDM), per JEDEC specification JESD22-C101(2) 1000
(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)
MIN MAX UNIT
VI Input voltage 3(1) 12 V
IO Output current 0 500 mA
TJ Operating virtual junction temperature 0 125 °C
(1) Minimum VI is equal to 3.0 V or VO(max) + 0.5 V, whichever is greater.

6.4 Thermal Information

THERMAL METRIC(1)(2) TLV2217 UNIT

RθJA Junction-to-ambient thermal resistance 81.6 31 22.5 °C/W
RθJC(top) Junction-to-case (top) thermal resistance 22.1 37.5 34.6 °C/W
RθJB Junction-to-board thermal resistance 32 11.3 8.8 °C/W
ψJT Junction-to-top characterization parameter 0.9 1.9 3 °C/W
ψJB Junction-to-board characterization parameter 31.5 11.2 7.8 °C/W
RθJC(bot) Junction-to-case (bottom) thermal resistance — 0.6 0.8 °C/W
(1) For more information about traditional and new thermal metrics, see the Semiconductor and IC Package Thermal Metrics application report.
(2) Maximum power dissipation is a function of TJ(max), RθJA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) − TA) / RθJA. Operating at the absolute maximum TJ of 150°C can affect reliability.
