LNBH23TPPR Description
LNBH23TPPR developed by STMicroelectronics is a monolithic voltage regulator and interface IC available in the Power SSO-24 ePAD package. It is able to provide the 13/18 V power supply and the 22 kHz tone signaling to the LNB down-converter in the antenna dish or to the multi-switch box, which makes it well suited for analog and digital satellite receivers/sat-TV, as well as sat-PC cards. Moreover, the LNBH23TPPR voltage regulator ensures extremely low component count, and low power dissipation, as well as simple design and I2C standard interfacing when operating.
