LM4132: without input voltage connecting 1.8v on vref Pin

Part Number: LM4132


We are using this IC in our product. in production our board will not be power on externally and we will program the board with programmer supply. in this programming time the reference IC verf pin will get 1.8V (because of programmer power supply ) and input pin of this ic will be floating. so are you seeing any risk on this??

we are using LM4132AMF-3.3V
