(1)

See Recommended Operating Conditions for more information about the core voltage for a specific device.

(2)

See the Layout Guidelines sections for details on connecting this pin.

(3)

PCB should directly route VDDS18_LDO to all of the VDDS18 pins.

(4)

On AM261x, the Analog LDO is connected internally to the 1.8V analog supply and therefore functions as a regular 1.8V output.
