    Hi Isaac,

    Vtap and SENSE pins are used to replace the needs of using resistor divider at feedback pin to set a fixed voltage; for this device, when FEEDBACK tied to VTAP, OUTPUT tied to SENSE, the output is set to 5V. If you don't plan to use Vtap and SENSE, you can just leave them open. 

    ERR pin is an open-drain output; when not in use, you can ground this pin or leave it open.
