When the output voltage rises to about 90% of its nominal voltage, power-good output is released. PG is high impedance when the device is disabled. An external pullup resistor must be connected between PG and OUT. The pullup resistor should be in the 100 k Ω to 1 MΩ range. If the power-good function is not used, the PG-pin should remain unconnected.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
