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. 1. Figure 25 provides thermal resistance versus PC board pad size. ELECTRICAL CHARACTERISTICS (VI − VO = 5.0 V; IO = 0.1 A, TJ = Tlow to Thigh (Note 2), unless otherwise noted.)

Tlow to Thigh = 0° to +125°C for LM317M Tlow to Thigh = −40° to +125°C for LM317MB, NCV317MB. 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. CAdj, when used, is connected between the adjustment pin and ground. 5. Thermal characteristics are not subject to production test. 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. |
