TPS7B4250-Q1: TPS7B4250QDBVRQ1客户电气性能测试出现引脚2未接地和引脚5未连接，请帮忙看下是否正常？

您好：

     TPS7B4250QDBVRQ1 客户测试发现与数据不符，但我们能确定货是正规渠道的，原装正品，请问为什么会出现这种情况呢？

After electrical test, we found there are inconsistence between the test result and datasheet. We found pin 2 is open circuit in the curve trace.

Please help to ask for MFG explanation about why pin 2 is not connected to ground and not connected to pin 5.

Please see the attached pictures.
Test Condition:
when one pin was tested, all the other pins are grounded.
Range: from -1.5v to +1.5v
Sampling point : 100
