Notes:
5. For a device mounted with the OUT leads on 50mm x 50mm 1oz copper that is on a single-sided 1.6mm FR4 PCB; device is measured under still
air conditions while operating in steady-state.
6. Same as Note 5, except mounted on 25mm x 25mm 1oz copper.
7. RθJL = Thermal resistance from junction to solder-point (at the end of the OUT leads).
8. Refer to JEDEC specification JESD22-A114 and JESD22-A115.
