(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.

(2) Continuous output current and operating junction temperature are limited by internal protection circuitry, but it is not recommended that
the device operate under conditions beyond those specified in this table for extended periods of time.
