使用TPS74601PQWDRBRQ1，输入电源3.3V，输出2.96V，电流300mA，Dropout voltage是按照最大310mV设计吗？上面提到VIN = VOUT(NOM) + 0.5 V这个是针对哪些应用场景的？

This 310mV dropout spec is with higher load current, you can see in figure 6.4:
That dropout decreases when load decreases. From 1A to 300mA it can decrease by 50%, meaning in your case the device should operate fine with 3.3V in and 2.96V out at 300mA load condition. Please let me know if this was not the original question.
