DESCRIPTION
Intended for analog and digital satellite STB
receivers/SatTV, sets/PC cards, the LNBP21 is a
monolithic voltage regulator and interface IC,
assembled
in
SO-20
and
PowerSO-20,
specifically designed to provide the power and the
13/18V, 22KHz tone signalling to the LNB down
converter in the antenna or to the multiswitch box.
In this application field, it offers a complete
solution with extremely low component count, low
