1. External heatsink is needed when used. 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 and output toGND short.

4. Load short protection will only prevent the IC from damaging if operating VCC<30 V

5. 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.
