P.6
Although ROHM is confident that the example application
circuit reflects the best possible recommendations, be sure
to verify circuit characteristics for your particular application.
Modification of constants for other externally connected
circuits may cause variations in both static and transient
characteristics for external components as well as this Rohm
IC. Allow for sufficient margins when determining circuit
constants.
