ARG81300 Single LNB Supply and Control Voltage Regulator

The ARG81300 is a single-channel low-noise block regulator (LNBR). The ARG81300 consists of a monolithic boost converter followed by a low-drop linear regulator. It is specifically designed to provide the power and the interface signals to an LNB down converter via coaxial cable in satellite TV rece.

ARG81300 Features
