Hello all,

 

I have an application in mind that would draw it's power from a car's 12 volt system. I was woried that it would strain the proto boards regulator as the 12 volts in car system while running can get up to 14 volts. I checked the specs on the LM2940 and it says it can handle an input voltage of up to 26 volts!

 

 My question is, if thats so why does the board specify a six to nine volt adapter? A 12 volt adapter should work fine right? 

 

Just wanted to check with the experts before I go out and fry a board!   :shocked:  

 

 

Thanks, 

Jim W.  :turn:
