Hi! Dear.
Can someone please suggest me how to make calculation for heatsink ? In my application I am using LM317A with 12v input volt. 1A is going to be output current. And output volt is going to be 4v. Could you please explain me how much heat dissipation would take place ?
And what size of heat sink should I use to prevent my board getting damage ? Is LM317A good enough for my application or should I try some thing else ? As I thought of using some resistor in series between supply volt (12v) and Vin of LM317 . But I am not sure whether it would be of great help ? If so what would be the value of resistor would i need ?
Please help me as I am just begginer in the design engineering.
Many thanks.
