Step 7 Assembly Step 4. Voltage regulator IC2

IC2 is the 78L05 voltage regulator. It's a small part with a black body and three leads on the bottom of the part. It has a flat face on one side were you will find the part number.

Install it onto the PCB as shown. You will have to bend the centre lead of the part back slightly to fit the triangular arrangement of the holes in the PCB.
