7. Tlow to Thigh = 0° to +125°C for LM317MA

Tlow to Thigh = −40° to +125°C for LM317MAB, NCV317MAB.

8. 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.

9. CAdj, when used, is connected between the adjustment pin and ground.

10.Thermal characteristics are not subject to production test.

11. 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.
