LNBH21PD-TR Description
Intended for analog and digital satellite STB receivers/SatTV, sets/PC cards, the LNBH21PD-TR is a monolithic voltage regulator and interface IC, assembled in POWER SO-20, specifically designed to provide the 13/1 8V power supply and the 22KHz tone signaling to the LNB down converter in the antenna or to the multi-switch box. In this application field, it offers a complete solution with an extremely low component count, and low power dissipation together with a simple design and I2CTM standard interfacing.
LNBH21PD-TR Features
