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.

1. T low to T high = 0 ° to +125 ° C; P max = 25 W for LM350T; T low to T high = ? 40 ° to +125 ° C; P max = 25 W for LM350BT
2. 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.
3. C Adj , when used, is connected between the adjustment pin and ground.
4. 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.
5. Thermal Resistance evaluated measuring the hottest temperature on the die using an infrared scanner. This method of evaluation yields very
accurate thermal resistance values which are conservative when compared to the other measurement techniques.
6. The average die temperature is used to derive the value of thermal resistance junction to case (average).
