LNBP8L - STMicroelectronics

LNBP8L LNB supply and control voltage regulator

Intended for analog and digital satellite receivers, the LNBP is a monolithic linear voltage regulator, assembled in the DFN8 (5 x 6) 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-s.
