The power-good (PG) pin is an open-drain output and can be connected to a regulated supply through an external pullup resistor. The maximum pullup voltage is listed as V_PG in the Section 6.3 table. For the PG pin to have a valid output, the voltage on the IN pin must be greater than V_UVLO(RISING), as listed in the Section 6.5 table. When V_OUT exceeds V_{PG(TH, RISING)}, the PG output is high impedance and the PG pin voltage pulls up to the connected regulated supply. When the regulated output falls below V_{PG(TH, FALLING)}, the open-drain output turns on and pulls the PG output low. If output voltage monitoring is not needed, the PG pin can be left floating or connected to ground.

By connecting a pullup resistor to an external supply, any downstream device can receive power-good (PG) as a logic signal that can be used for sequencing. Make sure that the external pullup supply voltage results in a valid logic signal for the receiving device.
