Hello guys,

One of my customers decided to use LM2991S/NOPB for their new products and they are routing board pattern of  the device for their proto type.

Then they found the deference between 2 type of the device package dimension diagrams.

One is the MECHANICAL DATA of KTT0005B in LM2991 datasheet (ver SNVS099I).

The other is MECHANICAL DATA of KTT(R-PSFM-G5) in TI package catalog.

Which is the correct mechanical data of LM2991S/NOPB package?

If KTT(R-PSFM-G5) is the correct package dimension, could you please give me the data of LAND PATTERN RECOMMENDATION?

Best regards,

Kazuya.
