PRODUCTION DATA.
When the device is configured for DDR termination applications, the REFOUT pin generates the DDR VTT reference voltage for the memory application. The device is capable of supporting both a sourcing and sinking load of 10 mA. The REFOUT pin becomes active when the REFIN voltage rises to 0.390 V and the VIN pin is above the UVLO threshold. When the REFOUT pin is less than 0.375 V, it is disabled and subsequently discharges to the GND pin through an internal 10-kΩ MOSFET. The REFOUT pin is independent of the EN pin state.
