(2) 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. (3) 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 the top and bottom of the board. Over operating temperature range (T J = -40°C to +125°C), VIN = VOUT(nom) + 0.5V (1), I OUT = 10mA, VEN = 1.7V, and COUT = 0.1µF, unless otherwise noted. Typical values are at T J = 25°C.
