○ Operation notes
・we are confident that the above applied circuit diagram should be recommended, but please thoroughly confirm its characteristics when using
it. In addition, when using it with the external circuit’s constant changed, please make a decision that allows a sufficient margin in light of the
fluctuations of external components and ROHM’s IC in terms of not only static characteristic but also transient characteristic.
