■ Cable length compensation
■ Internal over temperature protection
■ Backward current protection
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
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. 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).
