Frequently asked questions
What is the price of Heatsink for 78xx TO-220 Voltage Regulator in Egypt?
Heatsink for 78xx TO-220 Voltage Regulator currently costs 3.75 EGP in Egypt.
Where can I buy Heatsink for 78xx TO-220 Voltage Regulator in Egypt?

When do I need a heatsink on a 78xx regulator?
When the power it dissipates is high, for example a 12V input regulated down to 5V at a few hundred milliamps. Estimate the dissipated power as (Vin - Vout) x Iout to decide whether a heatsink is needed.
How do I mount it and do I need an insulator?
Apply thermal paste between the regulator and heatsink and fix them with a screw and nut. On 78xx regulators the metal tab is connected to ground, so an insulator is usually not needed, but confirm this in the datasheet for your exact part.
