The power-good (PG) pin is an open-drain output and can be connected to any 5.5 V or lower rail through an external pullup resistor. This pin requires at least 1.1 V on V_BIAS to have a valid output. The PG output is high-impedance when V_OUT is greater than V_IT + V_HYS. If V_OUT drops below V_IT or if V_BIAS drops less than 1.9 V, the open-drain output turns on and pulls the PG output low. The PG pin also asserts when the device is disabled. The recommended operating condition of PG pin sink current is up to 1 mA, so the pullup resistor for PG must be in the range of 10 kΩ to 1 MΩ. PG is only provided on the VQFN packages. If output voltage monitoring is not needed, then the PG pin can be left floating.
