Voltage regulators and transistors can get a little hot sometimes! Most chips state that they can cope with high currents and voltage drops, but running these devices in high-capacity situations can shorten their life. If you need to protect them from burning out, then add this nifty slide/clip-on** heat sink! No screws of thermal paste required, these heat sinks simply slide** onto any TO-220 size chip. These heat sinks have a thermal resistance of 28°C/W when connected to a TO-220 chip, which should let you dissipate around 4 Watts of power. ** These heatsinks are slide/Clip-on but you do need to give it a good push, approaching from the side with the angled corner. TO-220 chips are tough, so don't worry about damaging the casing - it needs a good tight hold!
