power-good detector (TPS60201 and TPS60203)
The power-good output is an open-drain output that pulls low when the output is out of regulation. When the
output rises to within 90% of its nominal voltage, the power-good output is released. Power-good is high
impedance in shutdown. In normal operation, an external pullup resistor must be connected between PG and
OUT, or any other voltage rail in the appropriate range. The resistor should be in the 100-kΩ to 1-MΩ range.
If the PG output is not used, it should remain unconnected.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. 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.
