+ : The parameter is measured with the recommended copper heat sink pattern on an 2-layer PCB, 11.7 in2 3.0×2.4 in2 in PCB,
1oz. copper, 3.0×1.5 in2 in coverage at Top-layer and Bottom-layer at 100% coverage (7.2in2).
++:The parameter is measured with the JEDEC standard test boards (multi-layer PCB).
