LDO Regulator Power Good Output Pin Question
Connect it through 10k to Vout. The pin is just a logic output, you can see from the second block diagram on page 3 of your datasheet that it's the output of a comparator. It would not be connected to an ADC. The pin could be used to drive a LED, the datasheet shows that it has sufficient current capability: 1mA is enough for an indicator.
