TPS798-Q1: handling of NC pins

Slava Prokopii

Part Number: TPS798-Q1

Hello.

There are 3 NC pins on TPS79801QDGNRQ1 device. I can see in datasheet that there is no internal connections to these pins, but I can't find a certain description on how this pins may be handled.

So I'm asking for support on this.

1. Can we connect NC contacts of TPS79801QDGNRQ1 (3,6,7 pins) to GND?

2. Can we left NC contacts of TPS79801QDGNRQ1 (3,6,7 pins) open?

Thank you.

    Hi Slava, 

    NC pins without internal connections can be left open or grounded. Grounded is prefered because the connections from the pins to the board can help better dissipate the heat to improve the thermal performance of the LDO.
