Operation Notes
1. Absolute Maximum Ratings
Exceeding the absolute maximum ratings (i.e. supply voltage, temperature) may cause damage to the device and make it impossible to
determine the failure mode (short/open). Therefore, when conditions exceeding the maximum ratings are anticipated, consideration
should be given to preventive countermeasures (e.g. fuses).
2. Application circuit
Although we can recommend the application circuits contained herein with a relatively high degree of confidence, we ask that you verify
all characteristics and specifications of the circuit as well as performance under actual conditions. Please note that we cannot be held
responsible for problems that may arise due to patent infringements or noncompliance with any and all applicable laws and regulations.
3. Operating conditions
Proper operation is guaranteed under the recommended conditions/specifications.
4. GND voltage
Ensure that the GND fin is connected and is at the lowest potential under any operating conditions, including transients.
5. Input supply voltage
Ensure that the Vcc pin is connected to the supply voltage.
6. Thermal design
Thermal designs should allow for sufficient margin for power dissipation under actual use.
7. Soldering
During mounting ensure that the OUT, Vcc, and GND pins are not shorted with one another. Carefully note IC orientation.
8. Operation in strong electromagnetic field
Operation in a strong electromagnetic field may cause malfunction.
9. Operation
The IC will turn ON when the voltage at the STBY pin is greater than 2.0V and will switch OFF if under 0.3V. Therefore, do not input
voltages between 0.3V and 2.0V. Malfunctions and/or physical damage may occur.
