Tlow to Thigh = 0° to +125°C for LM317L −40 ° to +125°C for LM317LB 4. Imax = 100 mA Pmax = 625 mW 5. 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. 6. CAdj, when used, is connected between the adjustment pin and ground. 7. 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. |
