What happens to the output voltage of the LM2744 if Vref falls to 0V?
The data sheet describes Vout is regulated with Vref down to 0.5V, but it is not clear what happens if the Vref falls below this. We have an applicaiton where the Vref control signal can be turned offf and drop to 0V but a valid VCC is still supplied to to the controller. Does the output also drop to 0V?
