2.1.1.1 Connect a Supply to J3 Connector

There is the bias supply EXTVCC (between 5.5 V and 10 V) for the LMG3100 driver. This driver supply is regulated to 5 V by the series LDO U2 (LP3869). This regulation verifies that the bias supply for the LMG3100 is accurate and is not exceeded beyond the gate voltage specifications. This user's guide refers to this supply as the driver bias supply.
