TPS7A80: Is it OK for the part to enters and quit UVLO frequently

Part Number: TPS7A80

Hi Team, 

Here is a question on TPS7A80. 

Vin=5V, Vout=3.3V. And there is a resistor from power supply to Vin pin. EN is always pulled high. 

With Vin ramp up, the part start to work but when it works, there is current through the resistor which makes voltage on Vin pin drops below UVLO. Then the part enters and quit UVLO frequently until Vin is high enough for the part to work. waveforms as below. Just want to check with you if it's OK for the part to work at such application, for example, will the part be latched off at such condition? To my opinion, it should be OK but just want to double check with you. Thanks. 

Ch3=Vout, Ch4=Vin.
