I have a question about TPS650061.

We do not use LDO2.

If we do not use LDO2, Please tell me about processing unused pins.

VINLDO2 : Floating?

EN_LDO2 : GND?

VLDO2 : Floating?

FB_LDO2 : Floating?

Best regards,

Thank you for your answer!

I want to check about your answer.

VINDLO2: GND

EN_LDO2: GND

VLDO2: Floating

FB_LDO2: Tied to VLDO2.

⇒We connect FB_LDO2 and VLDO2.
　Is it correct with the above understanding?
