Stresses exceeding Maximum Ratings may damage the device. 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.

2. T_low to T_high = 0° to +125°C for LM317M T_low to T_high = − 40° to +125°C for LM317MB, NCV317MB.
3. Load and line regulation are specified at constant junction temperature. Changes in V_O due to heating effects must be taken into account
separately. Pulse testing with low duty cycle is used.
4. C_Adj, 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.
