8.2.2.5 RPU - PGOOD Pullup Resistor

The PGOOD terminal of the LMZM23601 is an open-drain output. If the application requires a power-good flag, use a 100-kΩ pullup resistor from the PGOOD terminal to an external voltage rail. If a power-good function is not necessary, the PGOOD terminal can be left floating.
