kHrs.

2. Tlow to Thigh = 0° to +125°C for LM317M

Tlow to Thigh = − 40° to +125°C for LM317MB.

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. 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.
