• Drives up to three FETs

• Dynamic FET protection

• Drain current set by external resistor

• Regulated negative rail generator requires only 2 external capacitors

• Choice in drain voltage

• Wide supply voltage range

• Polarisation switch for LNBs

• QSOP surface mount package

APPLICATIONS

• Satellite receiver LNBs

• Private mobile radio (PMR)

• Cellular telephones
