(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. over recommended operating temperature range T J = -40 to 125°C, VEN = VIN, VIN = VOUT(nom) + 1 V (1), I OUT = 1 mA, C OUT = 10 µF, CNR = 0.01 µF (unless otherwise noted). Typical values are at 25°C.

(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. 3 |
