Standby terminal voltage
1. Always attach an outside heat sink when using the chip. In addition, the outside heat sink must be fastened onto
2. Connect the cooling fin to GND potential.
3. Avoid short circuit to V
4. The temperature protection circuit will be actuated at T
5. The overvoltage protection circuit starts its operation at V
6. For the standby voltage, a stabilized power supply of 3 V or higher should be used.
7. Only when being used in combination with the AN7077Z, this IC can operate up to the supply voltage of approx.
