... The ZNBG4003 is a four stage depletion mode FET bias controller intended primarily for satellite Low Noise Block’s (LNB’s), but its also suitable for other LNA applications such as those in found in PMR’s and microwave links. The ZNBG4003 provides each FET with a negative gate voltage and positive drain voltage with user programmable drain current. ...

... Furthermore if the negative rail experiences a fault condition, such as overload or short circuit, the drain supply to the FETs will shut down avoiding excessive current flow. To minimise PCB space ZNBG4003 is packaged in the 16 pin 3mm x 3mm QFN package. Device operating temperature is -40°C to 85°C to suit a wide range of environmental conditions ...

... To ease PCB layout, the pinout for the ZNBG4003 includes two Vcc pins. These pins are internally connected so only one of the pins needs to be powered for the device to function probable that the extra pin will help avoid the need for trace cross-over components or ground plane disruption from reverse side PCB links ...
