TWO-OUTPUT LNB SUPPLY AND CONTROL-
VOLTAGE REGULATOR
Intended for analog and digital satellite receivers, the low noise block converter regulator (LNBR) is a monolithic linear and switching
voltage regulator designed to provide power and interface signals to the LNB downconverter via the coaxial cable.
Because most satellite receivers have two antenna ports, the output
voltage of the regulator is available at one of two logic-selectable output terminals (LNBA, LNBB).
If the device is in stand-by mode (EN terminal LOW), both regulator outputs are disabled, allowing the antenna downconverters to be supplied and contr...
