The JEDEC low-K (1s) board design used to derive this data was a 3-inch
×
3-inch, two layer board with 2 ounce copper traces on top
of the board.
The JEDEC high-K (2s2p) board design used to derive this data was a 3-inch
×
3-inch, multilayer board with 1 ounce internal power and
ground planes and 2 ounce copper traces on top and bottom of the board.

Dropout is not measured for the TPS73018 and TPS73025 since minimum V

transitions high to low.
