Hi Team,

I am using TLV75718PDBVR in my design. I have attached schematics section for review.

Thanks in Advance.TLV75718PDBVR.pdf

Hi Shifali,

What's the load current on this device? The configuration looks good but I would be a little bit cautious using a ferrite bead at the input because if the load is abruptly disconnected the input could get an overvoltage condition.

Regards,

Nick

Hi Nick,

Thank you for your quick response.

The load should not consume more than 300mA of current.

Shifali,

This should be fine. My main concern is still the same but only if the load cuts off very quickly will it become an issue.

Regards,

Nick

Hi Nick,

Can you please let me know is it better to leave NC pin floating or connected to Ground.

The datasheet states the NC does not have internal connection but recommended layout has NC pin connected to Ground. Please let me know how to terminate NC pin.

Shifali,

Connecting NC to ground helps to improve thermal performance. Leaving it floating has no effect but it does not have the benefit to thermals.

Regards,

Nick
