BBB_SRM Section 5.4 #2

"An external LDOTLV70233 provides the 3.3V rail for the rest of the board."

There is not a TLV70233 in the BBB_SCH rev-C schematic diagrams.

There is a TL5209 3.3V regulator on the "BeagleBone Black Power Management" schematic, which I assume is the correct part number for the paragraph in the BBB_SRM. Further, it appears to be connected to the TPS65217C, and not the DC input. It may be helpful to mention that because several of us at ee.stackexchange were concerned that the TL5209's lower Max Vin reduced the DC input voltage headroom compared to the TPS65217C, which is not the case.

Thank you for the feedback. Please email Gerald Coley (gerald@beagleboard.org) directly since he is the one who prepares the SRM.
