How do I set the output voltage?
Use a resistor divider between the output, the feedback (FB) pin and ground. Output voltage = 1.23 V × (1 + R2/R1), where R2 connects output to FB and R1 connects FB to ground. Use the resistor values recommended in the datasheet.
Does it need external components?
Yes. A Schottky catch diode, an output inductor and input and output capacitors are required. Their values depend on the output voltage and current, so use the design table and layout guidance in the datasheet.
