LNBP8L,LNBP9L,LNBP10L,LNBP11L are monolithic linear voltage regulators for satellite receivers. They are designed to provide the powering voltages and the interfacing signals to the LNB down-converter. The regulator output can be logic controlled for 13 V or 18 V (typ.) by means of the EN/VSEL 3-state pin for remotely controlling the LNB.
