LM2901: Regarding thermal data for the part.

Part Number: LM2901

Hi team, 

kindly assist us with below mentioned queries..

For the part series LM2901M Datasheet specify only junction-ambient thermal resistance, but we need the 
junction-case or junction-board thermal resistance values for the thermal simulation. 
So, can you please provide these data as soon as possible.

Looking for your soonest response. 


Thank you!


Best Regards, 
Rohit Gaikwad.
