External heatsink should be fixed to the chassis. (2) Fin of the IC can be connected to GND. (3) Please prevent "Output to VCC short", "Output to GND short", “Pin Shift” in direction of Pin 7 and “Reverse Insertion" to avoid damaging the IC. (4) The temperature protection circuit will operate at Tj around 150˚C. However, if temperature decrease, the protection circuit will automatically be deactivated and resume normal operation. Eff.
