Hi team,
Could you please let me know about unused Vdd_alive (VLDO3) termination for TPS650250?
- Is it OK to leave it floating?
- Is the recommended output cap (2.2uF) needed?
- Is the load resistor needed?
Best regards,
Itoh

Hi Itoh,
Thanks for reaching out. VDD_alive (or VLDO3) on TPS650250 has a dedicated enable signal. If it is not used, then EN_Vdd_alive will have to be connected to GND and VDD_alive can be connected to GND or leave it floating. Just for your reference, here is the link to another E2E where the same question was asked.
Thanks,
Brenda
Hi Brenda,
I recognized that thread, but I wanted to make sure that it is OK to leave it floating.
Anyway, thank you for your support!
