LNBP14 Datasheet LNBP supply and control voltage regulator

Manufacturer: STMicroelectronics

General Description

Intended for analog and digital satellite receivers, the LNBP is a monolithic linear voltage regulator, assembled in PowerSO-20 and PowerSO-10, specifically designed to provide the powering voltages and the interfacing signals to the LNB downconverter situated in the antenna PowerSO-20 10 1 PowerSO-10 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 LOW), both regulator outputs are disabled to allow the antenna downconverters to be supplied/controlled by others satellite receivers sharing the same coaxial lines.
