3.10.1VDD Reference Regulator

The module incorporates a regulated voltage output VDD. The regulator provides a 2.8V output for use by
the customer application. This regulator can source up to 200mA of current to power any external digital
circuits. When the module started up by power on signal, The VDD is output. So it can be Illustrating
module start up.
Note: The VDD regulator is powered from the G510's main power supply, and therefore any current
sourced through this regulator originates from the G510 VBAT supply. The overall VBAT current
consumed by G510 is directly affected by the VDD operation. The G510 current consumption raises with
respect to the current sourced through VDD.
