). it says that ". A resistor can be pulled up to a particular supply voltage for monitoring." This is a Dual Output IC and the input voltage is 12V and it will regulate to 5 and 3.3 volts.
My question is what supply should pulled up the resistor? it is the 12V input or the 5V and 3.3V???
Because if I where to ask, I think I should pulled up the resistor to 5v and 3.3V since the purpose of PGOOD is to monitor the valid out voltage.
Hi FvM, I know that I can leave the PGOOD unconnected but since I am going to use in my circuit I think it is important, other than the connection of PGOOD in the power it is also connected to the Power Status Leds circuitry.
Again I take the risk to get called "rude" when referring to the datasheet.
12V? Datasheet says "Absolute maximum voltage for PGOOD is 6.0V". So 12V is no option.
Figure 1 in the datasheet shows them to be connected to INTVCC via 10k. This is a valid option.

But indeed it enables you to adjust on the device where you want to connect the PGOOD signal to.
If it´s a 3.3V powered device, use 3.3V
If it´s a 5V powered device, use 5V
