A 5-V, 10-mA linear regulator is integrated into the DRV835x family of devices and is available for use by external circuitry. This regulator can provide the supply voltage for low-current supporting circuitry. The output of the DVDD regulator should be bypassed near the DVDD pin with a X5R or X7R, 1-µF, 6.3-V ceramic capacitor routed directly back to the adjacent DGND or GND ground pin.
The DVDD nominal, no-load output voltage is 5 V. When the DVDD load current exceeds 10 mA, the regulator functions like a constant-current source. The output voltage drops significantly with a current load greater than 10 mA.
Use Equation 1 to calculate the power dissipated in the device because of the DVDD linear regulator.
For example, at VVM = 24 V, drawing 20 mA out of DVDD results in a power dissipation as shown in Equation 2.
