Re: Calculating heat dissipation

Thanks for finishing up the watts calculation..
Max current is 2Amps on the Voltage Regulator
Power dissipation is (16-12)*2 = 8W --- MAX

So if the room is 80 and the the heatsink is has a max operating temp of 80C- 176F,

Say the targeted HS is 140 (140-80=60deg.)
60/8.. 7.5degrees per watt

From here I guess the actual load is put in.
12V @ .250mA = 3W
Generating 24W of heat?

Need at least a heat sink that size?

How can it possibly run a 2AMPS??-- Reduce the power dissipation so
Vin = Vout OR Vin < Vout
16ohm "R" 5W should bring Vin to 12VDC.

Thanks,
Mitch
