... The S-1721 Series requires an output capacitor between the VOUT and VSS pin for phase compensation. Operation is stabilized by a ceramic capacitor with an output capacitance of 1.0 µF or more over the entire temperature range. When using an OS capacitor, tantalum capacitor, or aluminum electrolytic capacitor, the capacitance must be 1.0 µF or more ...

... Pull-down/pull-up resistor (S-1721 Series and D types) In the S-1721 Series and D types, the ON/OFF pin is internally pulled up to VIN or pulled down to VSS, so the VOUT pin is in the VSS level when in the floating status. In A/B (1ch only) and C (2ch only), the ON/OFF pin is connected to VIN (2ch only)/C (1ch only)/D type, the ON/OFF pin is connected to VSS ...

... The voltage regulator may oscillate when the impedance of the power supply is high and the input capacitor is small or an input capacitor is not connected. Note that, if the capacitance of the output capacitor is greater than that of the input capacitor, the voltage regulator may oscillate. ...
