for each layer of a four-layer board; the inner layers are 1 oz. (35 µm), while the outer layers are 2 oz. (70 µm). A

typical curve of maximum load current versus ambient temperature, for both the LM53603 and LM53602, is

input voltage of 12 V. It must be remembered that the data shown in these graphs are for illustration only and the

actual performance in any given application depends on all of the factors mentioned above.
