TLV9002: known issue?: light sensitive current draw change on VCC with package X2QFN (RUG)

Part Number: TLV9002
Other Parts Discussed in Thread: TEST, OPA330

Hi

We use X2QFN (RUG) (R-PQFP-N10) package of the TLV9002S.

Under open lab conditions we see changing current draws depending on the lab light environment (up to 0.5mA).

Finding this was somewhat tiresom as the design is low power.

It's not an issue in the final product within the enclosure but might be a toppic during testing and engineering.

Is this a known flaw of this small package? Any further (published) information on this?

We know that some CSP do show similar behaviours.
