1.0 F or more  
Caution Generally a series regulator may cause oscillation, depending on the selection of external parts.  
Confirm that no oscillation occurs in the application for which the above capacitors are used.  
Selection of Input and Output Capacitors (CIN, CL1, CL2)  
The S-1721 Series requires an output capacitor between the VOUT pin and VSS pin for phase compensation.  
Operation is stabilized by a ceramic capacitor with an output capacitance of 1.0 F or more over the entire temperature  
range. When using an OS capacitor, a tantalum capacitor, or an aluminum electrolytic capacitor, the capacitance must  
be 1.0 F or more.  
The value of the output overshoot or undershoot transient response varies depending on the value of the output  
capacitor. The required capacitance of the input capacitor differs depending on the application.  
The recommended capacitance for an application is CIN 1.0 F, CL1 1.0 F, CL2 1.0 F; however, when selecting  
the output capacitor, perform sufficient evaluation, including evaluation of temperature characteristics, on the actual  
device.

This voltage regulator has the low dropout voltage due to its built-in low on-resistance transistor.  
2. Output voltage (VOUT  
)
The accuracy of the output voltage is ensured at 1.0% under the specified conditions of fixed input voltage*1, fixed  
output current, and fixed temperature.  
*1. Differs depending on the product.  
Caution If the above conditions change, the output voltage value may vary and exceed the accuracy  
range of the output voltage. Refer to the “Electrical Characteristics” and “Characteristics  
(Typical Data) (Per Circuit)” for details.

Operation  
1. Basic operation  
Figure 23 shows the block diagram of S-1721 Series.  
The error amplifier compares the reference voltage (Vref) with feedback voltage (Vfb), which is the output voltage  
resistance-divided by feedback resistors (Rs and Rf). It supplies the gate voltage necessary to maintain the constant  
output voltage which is not influenced by the input voltage and temperature change, to the output transistor.

2. Output transistor  
In the S-1721 Series, a low on-resistance P-channel MOS FET is used as the output transistor.  
Be sure that VOUT does not exceed VIN 0.3 V to prevent the voltage regulator from being damaged due to reverse  
current flowing from the VOUT pin through a parasitic diode to the VIN pin, when the potential of VOUT became higher  
than VIN.

3. ON/OFF pin 1 and 2  
These pins start and stop the regulator.  
When the ON/OFF pin is set to OFF level, the entire internal circuit stops operating, and the built-in P-channel MOS  
FET output transistor between the VIN pin and VOUT pin is turned off, reducing current consumption significantly.  
The VOUT pin becomes the VSS level due to the internally divided resistance of several hundreds kbetween the  
VOUT pin and the VSS pin.  
Note that the current consumption increases when a voltage of 0.3 V to 1.2 V (@Ta = 25C) is applied to the  
ON/OFF pin.  
The ON/OFF pin is configured as shown in Figures 24 and 25. In the S-1721 Series A, B C, and D type, the  
ON/OFF pin is internally pulled up to VIN pin or pulled down to VSS pin when in the floating status, so the VOUT pin  
is set to the VSS level.  
In the S-1721 Series E, F, G and H type, the ON/OFF pin is not internally pulled up or pulled down, so do not use it  
in the floating status.  
When not using the ON/OFF pin in the S-1721 Series E, F, G, and H type, connect the ON/OFF pin to the VIN pin in  
the E/F (1ch only), and G (2ch only) type. In the F (2ch only)/G (1ch only) and H type, connect the ON/OFF pin to  
the VSS pin.

S-1721 Series  
4. Overcurrent protection circuit  
The S-1721 Series has a built-in overcurrent protection circuit having the characteristics shown in “(1) Output  
Voltage vs. Output Current (When Load Current Increases) (Ta = 25°C)” in “Characteristics (Typical Data)  
(Per Circuit)”, in order to protect the output transistor against an excessive output current and short circuiting  
between the VOUT pin and the VSS pin. The current when the output pin is short-circuited (Ishort) is internally set at  
approx. 150 mA typ., and the normal value is restored for the output voltage, if releasing a short circuit once.  
Caution This overcurrent protection circuit does not work as for thermal protection. If this IC long keeps  
short circuiting inside, pay attention to the conditions of input voltage and load current so that,  
under the usage conditions including short circuit, the loss of the IC will not exceed power  
dissipation of the package.  
5. Pull-down/pull-up resistor (S-1721 Series A, B, C, and D type)  
In the S-1721 Series A, B, C, and D type, the ON/OFF pin is internally pulled up to VIN pin or pulled down to VSS  
pin in the floating status, so the VOUT pin is set to VSS level.  
In A/B (1ch only) and C (2ch only), the ON/OFF pin is connected to VIN pin,  
In B (2ch only)/C (1ch only)/D type, the ON/OFF pin is connected to VSS pin;  
Note that during operation in these cases, the current consumption of the IC is generated as much as the current  
which flows into a pull-up resistor of 2.6 Mor a pull-down resistor of 2.6 M.

Precautions  
Wiring patterns for the VIN pin, the VOUT pin and GND should be designed and that the impedance is low. When  
mounting an output capacitor between the VOUT pin and VSS pin (CL1, CL2), a capacitor for stabilizing the input  
between the VIN pin and the VSS pin (CIN), the distance from the capacitors to these pins should be as short as  
possible.  
Note that generally the output voltage may increase when a series regulator is used at low load current (1.0 mA or  
less).  
Note that generally the output voltage may increase due to the leakage current from an output driver when a series  
regulator is used at high temperature.  
Generally a series regulator may cause oscillation, depending on the selection of external parts. The following  
conditions are recommended for the S-1721 Series. However, be sure to perform sufficient evaluation under the  
actual usage conditions for selection, including evaluation of temperature characteristics. Refer to “(5) Example of  
Equivalent Series Resistance vs. Output Current Characteristics (Ta = 25C)” in “Reference Data (Per  
Circuit)” for the equivalent series resistance (RESR) of the output capacitor.  
Input capacitor (CIN) :  
1.0 F or more  
1.0 F or more  
Output capacitor (CL1, CL2) :  
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.  
Note that an oscillation may occur when the load current is high (100 mA or higher) and the difference between the  
voltage input and output is around the dropout voltage if the inductance of the power supply is high. Perform  
sufficient evaluation including electrical characteristics under the actual use conditions to select an input capacitor.  
Concerning the fluctuation of output voltage due to power-supplying and load, confirm with the actual device.  
Overshoot may occur in the output voltage momentarily if the voltage is rapidly raised at power-on or when the  
power supply fluctuates. Sufficiently evaluate the output voltage at power-on with the actual device.  
The application conditions for the input voltage, the output voltage, and the load current should not exceed the  
package power dissipation.  
Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in electrostatic  
protection circuit.  
In determining the output current, attention should be paid to the output current value specified in Table 10 in “  
Electrical Characteristics” and footnote *5 of the table.
