Part Number: TLV62130

Here in my company we are using MYIR z-turn board.  On that board they used TLV62130 to convert 5 v to 3.3 v.  There are two types of powering is available one is USB and another one is 5v adapter. While using the USB powering, it works just fine.  But when using the adapter, PG output pin voltage fluctuates a lot (0 to 1.46 v - 72Hz).So the processor can't be turned on. the USB powering gives 0 v to 3.3 v. I have confirmed these thing using a oscilloscope. Please reply for this question, thank you.
