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.

Minimum V
is 2.7V or V
+ V
, whichever is greater.
Dropout is not measured for the TPS73018 and TPS73025 since minimum V
= 2.7V.
For adjustable versions, this applies only after V
IN
is applied; then V
EN
transitions high to low.
