LNBH25LPQR Description
LNBH25LPQR, assembled in the QFN24 package, is a type of LNB supply and control voltage regulator intended for analog and digital satellite receivers. It is able to provide the powering voltages and the interfacing signals to the LNB downconverter situated in the antenna via the coaxial cable. The voltage output by the regulator can be accessible at one of two logic-selectable output pins (LNBA, LNBB) because most satellite receivers have two antenna ports. others satellite receivers with the same coaxial cable will supply or control the antenna downconverters on the condition that the IC is powered and put in Stand-by (EN pin LOW) and both regulator outputs are disabled.
