Get the most out of your regulators, transistors, and other TO-220 packaged chips by clipping on a heat sink. Your transistor or regulator may advertise it can handle high currents but when multiplied by the drop voltage, the Wattage may be too high for the bare chip! Most TO-220s can dissipate about 2W's worth without a sink. https://www.adafruit.com/product/977
