STMicroelectronics LNBK20D2 LNB Supply and Control Voltage Regulator Datasheet

The LNBK20D2 is a monolithic linear voltage regulator designed for analog and digital satellite receivers to provide powering voltages and interfacing signals to the LNB downconverter situated in the antenna via the coaxial cable. It has the same functionality as the LNBP1X and LNBP20 series, but with a reduced output current capability.

About this manual

The LNBK20D2 is a monolithic linear voltage regulator in an SO-20 package designed for analog and digital satellite receivers. It provides powering voltages and interfacing signals to the LNB downconverter situated in the antenna via the coaxial cable. The device features two logic-selectable output pins (LNBA, LNBB) and offers the same functionality as the LNBP1X and LNBP20 series but at a reduced output current capability.
