... LNBP12 LNBP13 LNBP14 LNBP15 LNBP16 LNBP20 May 2007 LNBP20 / LNBP1X series TM PowerSO-20 via the coaxial cable. Since most satellite receivers have two antenna ports, the output voltage of the regulator is available at one of two logic-selectable output pins (LNBA, LNBB). When the IC is powered and put in Stand-by (EN pin ...
