Warning

The base current of transistor TLIN in the linear regulator of the BPP pin circuit may not be sufficient to provide BPP-Pin maximum current IS2 at full load. The power supply for the internal circuitry will be derived from the drain tap, hence increasing the device internal dissipation.

Reduce resistor RLIN value, or use transistor TLIN with higher gain. Alternatively, use the default RLIN value.
