(1)

The JEDEC low-K (1s) board design used to derive this data was a 3-inch x 3-inch, two layer board with 2 ounce copper traces on top

of the board.

(2)

The JEDEC high-K (2s2p) board design used to derive this data was a 3-inch x 3-inch, multilayer board with 1 ounce internal power and

ground planes and 2 ounce copper traces on top and bottom of the board.

(1)

Minimum VIN is 2.7 V or VOUT + VDO, whichever is greater.

(2)

Dropout is not measured for the TPS73018 and TPS73025 since minimum VIN = 2.7 V.

(3)

For adjustable versions, this applies only after VIN is applied; then VEN transitions high to low.
