LNBP11 LNBP supply and control voltage regulator

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 .

Features

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. In this occurrence the device will limit at 3 mA (max) the backward current that could flow from LNBA and LNBB output pins to GND. (See continuous description).
