(1) For more information about traditional and new thermal metrics, see the Semiconductor and IC Package Thermal Metrics application note.

(2) Thermal performance results are based on the JEDEC standard of 2s2p PCB configuration. These thermal metric parameters can be further improved by 35-55% based on thermally optimized PCB layout designs. See the analysis of the Impact of board layout on LDO thermal performance application report.
