at 16 V may be limited by power loss in the linear regulator.
2 Guaranteed
by worst case process simulations and system characterization. Not production tested.
3 LNB output ripple and noise are dependent on component selection and PCB layout. Refer to the Application Schematic and PCB layout
recommendations. Not production tested.
4 Current from the LNB output may be limited by the choice of Boost components.
