Typical Performance Characteristics
LD Specific Characteristics
Note 13: This curve shows the LM4850LD’s thermal dissipation ability at different ambient temperatures given the exposed-DAP of the part is soldered to a plane
of 1oz. Cu with an area given in the label of each curve. This label also designated whether the plane exists on the same (top) layer as the chip, on the bottom layer,
or on both layers. Infinite heatsink and unattached (no heatsink) conditions are also shown.
