ADP125: Protection diode required?

Hi everyone,

I'm designing a circuit with some ADP125 LDOs for the analog supplies. In the abs. max. ratings, there is a requirement for VOUT:

VOUT to GND | -0.3V to VIN

This would clearly indicate that the regulator needs a reverse diode from VOUT to VIN, however, this is not present on the evaluation board. Since the pass transistor is a P-channel MOSFET, I'd expect there to be an internal diode anyway. So is there still an external Schottky required?

Thanks. Best regards,
