PRODUCTION DATA.
Refer to the PDF data sheet for device specific package drawings
The LMZM33606 has a built-in power-good signal (PGOOD) that indicates whether the output voltage is within its regulation range. The PGOOD pin is an open-drain output that requires a pull-up resistor to a nominal voltage source of 15 V or less. The maximum recommended PGOOD sink current is 5 mA. A typical pull-up resistor value is between 10 kΩ and 100 kΩ.
Once the output voltage rises above 90% (typical) of the set voltage, the PGOOD pin rises to the pull-up voltage level. The PGOOD pin is pulled low when the output voltage drops lower than 90% (typical) or rises higher than 110% (typ) of the nominal set voltage.
Internal to the device, a 100-kΩ pull-up resistor is placed between the PGOOD pin and the PGOOD_PU pin. Applying a pull-up voltage directly to the PGOOD_PU pin, eliminates the need for an external pull-up resistor.
