The power good output is low when the output voltage is below the nominal value. The power good becomes high impedance once the output is within 5% of regulation. The PG pin is an open-drain output and is specified to typically sink up to 1 mA. This output requires a pullup resistor to be monitored properly. The pullup resistor cannot be connected to any voltage higher than the input voltage of the device. The PG output is low when the device is disabled, in thermal shutdown, or in UVLO. The PG output can be left floating if unused.
