Hi Naveen,

REG1 and REG2 are not powered on by default. This is because each of these can be programmed to different voltages (2.5V, 3.0V, 3.3V, 5.0V).

I recommend this document to help you get started: https://www.ti.com/lit/pdf/slua991

It shows how to set up the basic settings including the regulators.

Best regards,

Matt
