Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.

Thermal Resistance Junction−to−Case, T Package RqJC − 5.0 − °C/W 1. Tlow to Thigh = 0° to +125°C, for LM317T, D2T. Tlow to Thigh = − 40° to +125°C, for LM317BT, BD2T, Tlow to Thigh = − 55° to +150°C, for NCV317BT, BD2T. 2. Imax = 1.5 A, Pmax = 20 W 3. Load and line regulation are specified at constant junction temperature. Changes in VO due to heating effects must be taken into account separately. Pulse testing with low duty cycle is used. 4. Power dissipation within an IC voltage regulator produces a temperature gradient on the die, affecting individual IC components on the die. These effects can be minimized by proper integrated circuit design and layout techniques. Thermal Regulation is the effect of these temperature gradients on the output voltage and is expressed in percentage of output change per watt of power change in a specified time. 5. CAdj, when used, is connected between the adjustment pin and ground. 6. Since Long−Term Stability cannot be measured on each device before shipment, this specification is an engineering estimate of average stability from lot to lot. |
