PRODUCTION DATA.
This pin provides a digital flag which is low when either EN is low or the start-up sequence described earlier in this section has not been completed. READY goes high when EN is high and start-up is complete. The pin is driven by an open drain pull-down capable of sinking 3 mA while holding 0.4 V on the pin. Connect a resistor of 10 kΩ to VCC to provide the pull-up.
