The voltage regulator has 3 pins:

Pin 1: V in (5 V)

Pin 2: V out (3.3 V)

Pin 3: "Adjust"

Use a pair of pliers to carefully bend pin 1 down 90°, pin 3 up 90° and pin 2 up as far as possible without touching pin 3.

Do not worry about getting exact angles, as you will likely need to adjust the pins when you go to fit the IC to the PCB.

Do not repeatedly bend and unbend the pins, as repeated bending will weaken the metal and eventually cause it to break.
