11. 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.
12. 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.
