Description
Intended for analog and digital satellite receivers, the LNBP is a monolithic linear voltage regulator, assembled in the DFN8 5x6 and IPPAK packages, specifically 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. When the IC is powered and put in standby (EN/VSEL pin at high impedance), the regulator output is disabled. In order to reduce power dissipation, the LNBP10L/11L versions (on DFN
