You can get single-chip current limiters for LED driver applications. A CL2N8-G for example.
In some applications you can also use almost any linear voltage regulator - put a resistor between your linear regulator's ground and output pins, and you'll get a constant current.
Of course if your application involves the amount of power dissipation that requires a heatsink, you'll probably end up with a discrete component for that anyway :)

- amelius 2y agoLet's say I have a voltage source of 48V, and I want to limit current in my system to 4.5A, precisely, and with overheating protection. I could be wrong but I don't think the led-driver and voltage regulator solutions would fall in this range. Also, a heatsink would not be required if the duration in which the current needs limiting is small.
