DRV10987: Regulator Circuitry

Part Number: DRV10987


Tool/software:

Hello,

For using the DRV10987's voltage regulator in linear mode, is it required to use a Zener diode in conjunction with the 39 ohm resistor, as shown in the schematic for the EVM board? What are the specs of this diode (Zener voltage, power/current rating, etc.)?

In my setup, I am using only the 39 ohm resistor, but I repeatedly obtain the VREG_OC (overcurrent on VREG pin) fault.

Thanks
