Part Number: TLV61220

I would like to confirm the variation of VFB.

In the datasheet, there are min/max and typ. value.

But the customer want the actual measured value or the distribution histogram with several lots.

Could you please give it ?

Best regards,

Hi Yamauchi
We can guarantee almost ICs are in the range from min to max of datasheet.
why do customer want to know VFB distribution?

Dear Jing-san,

Thank you for your response.

I have confirmed the reason.

They previously had the problem of VFB in similar device.

So they requested actual data.

If you can, could you please provide actual value of VFB?

Best regards,
