Hello experts,

Is the Junction-to-ambient thermal resistance of LMG3100R017 in the datasheet acquired with or without top side cooling? In other word, heat sink is attached to its top side metal?

Thanks,

Kento

Hi Kento,

The thermal resistance is obtained without any heatsink on top.

This value is estimated according to the procedure outlined in Section 1 of this application note:

Thanks,

John
