TPS51200: Capacitance on REFOUT pin 2

PAN-M

Part Number: TPS51200

Dear team,

Please teach me a meaning of "The REFOUT pin can not open," .
When I do not use this pin, is it OK if I connect 0.1uF?

Best Regards,

Hi PAN-M,

VO voltage follow REFOUT voltage.

Even REFOUT signal is not used for external circuit, a bypass cap is needed to keep REFOUT voltage stable.

So it is fine to connect 0.1uF cap when you don't use this pin.

Thanks

Qian
