Load of LDOs
According to a note in U31 data sheet:
When V BIAS and V EN are present and V IN is not supplied, this device outputs approximately 50 μA of current from OUT. Although this condition does not cause any damage to the device, the output current can charge up the OUT node if total resistance between OUT and GND (including external feedback resistors) is greater than 10 kΩ.
In CaR 1.1, it's more than 10kΩ and potentially (although in unlikely coincidence), we could damage a DUT chip if this node is charged up.
