Intended for analog and digital satellite receivers, the LNBP is a monolithic linear voltage regulator, assembled in HeptawattTM, specifically designed to provide the powering voltages and the interfacing signals to the LNB down-converter. The regulator output can be logic controlled to be 13V or 18V (typ.) by mean of the VSEL pin for the remote controlling .
, the regulator has 2 supply inputs (VCC1 and VCC2). They must be powered respectively at 15V (min.) and 22V (min.), and an internal switch will automatically select the appropriate supply voltage according to the selected output voltage. The TONE pin (only for the LNBP9 version) activates the internal oscillator so that the DC output is modulated by a 22KHz square wave. This internal oscillator is factory trimmed within a Table 1: Order Codes TYPE LNBP8 LNBP9 tolerance of +/- 2KHz, thus no further adjustment or external components are required. A burst coding of the 22KHz tone can be accompl.
