Product Summary
The LNBP20PD is a LNB supply and control voltage regulator parallel interface. The LNBP20PD is a monolithic linear voltage regulator, assembled in Multiwatt-15, PowerSO-20 and PowerSO-10, specifically designed to provide the powering voltages and the interfacing signals to the LNB downconverter situated in the antenna 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 of the LNBP20PD is powered and put in Stand-by (EN pin LOW), both regulator outputs are disabled to allow the antenna downconverters to be supplied/controlled by others satellite receivers sharing the same coaxial lines. In this occurrence the device will limit at 3mA (max) the backward current that could flow from LNBA and LNBB output pins to GND.
