If you haven't added him in with a mod, then he's simply not there. There's no way to spawn him in the vanilla version of the game.

You can't mod the PS3 version, so you can't add Herobrine in.
I don't believe that Herobrine is in vanilla Minecraft. There are videos on YouTube that used the Single Player Commands mod to spawn the discontinued 'monster' (human) mob with the texture modified to look like the legendary Herobrine. The SPC command is 'spawn monster'. There are 'Herobrine' mods, but I have not looked into those.
Whichever Herobrine mod you are using will say how to make Herobrine appear and what you can do what he does, each mod will be different.
Herobrine doesn't spawn.
The only way to spawn herobrine in minecraft is to use mods as you cannot spawn him in vanilla minecraft.
