... If further thermal improvements are needed, double sided, multilayer PC boards with large copper areas and/or airflow are recommended. The AP1512/A (TO-263 package) junction temperature rises above ambient temperature with a 2A load for various input and output voltages. This data was taken with the circuit operating as a buck switching regulator with all components mounted board to simulate the junction temperature under actual operating conditions ...
