■NOTES ON USE
1. Use this IC within the stated maximum ratings. Operation beyond these limits may cause degrading or permanent
damage to the device.
2. The power supply input pin voltage drops by the resistance between power supply and the VIN pin, and by through
current at operation of the IC. At this time, the operation may be wrong if the power supply input pin voltage falls below
the minimum operating voltage range. In CMOS output, for output current, drops in the power supply input pin voltage
similarly occur. Moreover, in CMOS output, when the VIN pin and the sense pin are short-circuited and used,
oscillation of the circuit may occur if the drops in voltage, which caused by through current at operation of the IC, exceed
the hysteresis voltage. Note it especially when you use the IC with the VIN pin connected to a resistor.
3. When the setting voltage is less than 1.0V, be sure to separate the VIN pin and the sense pin, and to apply the voltage
over 1.0V to the VIN pin.
4. Note that a rapid and high fluctuation of the power supply input pin voltage may cause a wrong operation.
5. When there is a possibility of which the power supply input pin voltage falls rapidly (e.g.: 6.0V to 0V) at release
operation with the delay capacitance pin (Cd) connected to a capacitor, use a schottky barrier diode connected between
the VIN pin and the Cd pin as the Figure 3 shown below.
6. In N-ch open drain output, a pull-up resistor connected to the output voltage pin should be 100k-200kΩ.
