Product Summary

Intended for analog and digital satellite receivers, the LNBK20PD-TR is a monolithic linear voltage regulator,assembled in Multiwatt-15, PowerSO-20 and PowerSO-10, specifically designed to provide thepowering voltages and the interfacing signals tothe LNB downconverter situated in the antennavia the coaxial cable. The LNBK20PD-TR has the same functionality of the LNBP1X and LNBP20 series, at a reduced output current capability. Since most satellite receivers have two antenna ports, the output voltage of the regulator is available at one of twologic-selectable output pins (LNBA, LNBB). When the IC is powered and put in Stand-by (EN pinLOW), both regulator outputs are disabled to allow the antenna down converters to be supplied/controlled by others satellite receiverssharing the same coaxial lines. In this occurrence the LNBK20PD-TR will limit at 3 mA (max) the backward current that could flow from LNBA and LNBB output pins to GND.

Parametrics

LNBK20PD-TR absolute maximum ratings: (1)DC Input Voltage: 28V; (2)Logic Input Voltage: -0.5 to 7V; (3)Bypass Switch Current: 900mA; (4)Storage Temperature Range: -40 to 150℃; (5)Operating Junction Temperature Range: -40 to 125℃.

Features

LNBK20PD-TR features: (1)reduced output current version; (2)complete interface for two LNBs remote supply and control; (3)LNB selection and stand-by function; (4)fast oscillator start-up; (5)cable length compensation; (6)internal over temperature protection; (7)backward current protection.
