Stingray X/Ku Phased Array reference schematic questions

Question

Hi, 
 For preparing the new prj, I'm researching Sting Array Schematic and BOM (059522a revision). 
 Then I just found some parts in schematic file but it's not included in BOM. 
 Please help to share it in the detail. (what's component? How it work?...) 
 - Schematic page 12: Reguators Part 
 
 - Schematic page 13: Positive/Negative Part

Hello, 
 The DC regulator components are indeed on the BOM and the schematic. The schematic details the circuitry for all the DC rails, which are derived from an external +12 VDC supply via the P1/P2 connector. Links to the parts can be found on the wiki page.
