7.3.6 Power Good (PGOOD) Function

The LMZM23601 has a built-in power-good signal presented at the PGOOD terminal. This signal indicates whether the output voltage is within the regulation window. The PGOOD terminal is an open-drain output that requires a pullup resistor to a nominal voltage source of 15 V or less. The absolute maximum PGOOD sink current is 8 mA. Typically, TI recommends a pullup resistor value between 10 kΩ and 100 kΩ. Refer to Electrical Characteristics for the power-good thresholds and hysteresis for undervoltage and overvoltage detection.
