TPS613221AEVM: No-load current ( Quiscent current )

Part Number: TPS613221AEVM


I am testing with TPS613222A and TPS613221A

I need very little quiescent current.

so I have some questions.

When I tested TPS613222A, the no-load current was about 22uA.

However, when I tested TPS613221A, the no-load current was exceeded 1mA.

In the datasheet, they all come out  below 6uA ( Quiescent current ),

No-load current is equal to quiescent current, right?

I don't know why the no-load current is over 6uA when I test them.

Can you explain why?

and could you let me know how to lower the quiescent current like the datasheet of TPS61322x

My circuits is as follows.

When testing TPS613221A, it was tested by replacing only TPS613222A in the above circuit

please help me
