GND CIN is a capacitor for stabilizing the input. A ceramic capacitor of 1.0 µF or more can be used for CL1 and CL2. Figure Caution 21 The above connection diagram and constant will not guarantee successful operation. Perform thorough evaluation using the actual application to set the constant. Condition of Application Input capacitor (CIN) : Output capacitor (CL1, CL2) : 1.0 µF or more 1.0 µF or more (ceramic capacitor) Caution A general series regulator may oscillate, depending on the external components. 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 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. 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 µF, CL1 ≥ 1.0 µF, CL2 ≥ 1.0 µF; however, when selecting the output capacitor, perform sufficient evaluation, including evaluation of temperature characteristics, on the actual device.

Basic operation Figure 23 shows the block diagram of S-1721 Series. The error amplifier compares the reference voltage (Vref) with 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.

Output transistor 23 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 inverse current flowing from the VOUT pin through a parasitic diode to the VIN pin. 18 Seiko Instruments Inc. SUPER-SMALL PACKAGE 2-CIRCUIT HIGH RIPPLE-REJECTION LOW CURRENT CONSUMPTION LOW DROPOUT CMOS VOLTAGE REGULATOR Rev.1.1_00 S-1721 Series 3. ON/OFF pin 1 and 2 These pins start and stop the regulator. When the ON/OFF pin is set to the power-off level, the entire internal circuit stops operating, and the built-in Pchannel MOS FET output transistor between the VIN and VOUT pin is turned off, in order to reduce the current consumption significantly. The VOUT pin is set to the VSS level by the internal dividing resistor of several hundred kΩ which is placed between the VOUT and VSS pin. Note that the current consumption increases when a voltage of 0.3 V to 1.2 V (@Ta = 25°C) 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 types, the ON/OFF pin is internally pulled up to VIN or pulled down to VSS 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 types, do not use S-1721 Series in the floating status because the ON/OFF pin is not internally pulled up or pulled down. When not using the ON/OFF pin in the S-1721 Series E, F, G, and H types, connect the ON/OFF pin to the VIN pin in the E, F (1ch only), and G (2ch only) types. In the F (2ch only), G (1ch only) and H types, connect the ON/OFF pin to the VSS pin.

Overcurrent protector The S-1721 Series has a built-in overcurrent protector having the characteristics shown in (1) Output Voltage vs. Output Current (Ta = 25°C) in “ Characteristics (Typical Data) (Per Circuit)” to protect the output transistor against an excessive output current and short circuiting between the VOUT and VSS pin. The current (Ishort) when the output pin is short-circuited is internally set at approximately 150 mA (Typ.), and the initial value is restored for the output voltage, if releasing a short circuit once. Note that the overcurrent protect circuit does not provide a thermal protection function, therefore pay attention to the conditions of input voltage and load current so that the IC’s loss under the usage conditions, including the short circuit conditions, does not exceed the package power dissipation if the condition in which a short circuiting continues for a long time. 5. Pull-down/pull-up resistor (S-1721 Series A, B, C, and D types) In the S-1721 Series A, B, C, 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, In B (2ch only)/C (1ch only)/D type, the ON/OFF pin is connected to VSS; 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 MΩ or a pull-down resistor of 2.6 MΩ. 20 Seiko Instruments Inc. SUPER-SMALL PACKAGE 2-CIRCUIT HIGH RIPPLE-REJECTION LOW CURRENT CONSUMPTION LOW DROPOUT CMOS VOLTAGE REGULATOR Rev.1.1_00 S-1721 Series Precautions • Wiring patterns for the VIN, VOUT and GND pins should be designed so that the impedance is low. When mounting an output capacitor between the VOUT and VSS pin (CL1, CL2) and a capacitor for stabilizing the input between VIN and VSS pin (CIN), the distance from the capacitors to these pins should be as short as possible. • Note that the output voltage may increase when a series regulator is used at low load current (1.0 mA or less). • Note that the output voltage may increase due to the leakage current from a 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 this IC. However, be sure to perform sufficient evaluation under the actual usage conditions for selection, including evaluation of temperature characteristics. See “(5) Example of Equivalent Series Resistance vs. Output Current Characteristics (Ta = 25°C)” in “ Reference Data (Per Circuit)” for the equivalent series resistance (RESR) of the output capacitor. Input capacitor (CIN) : Output capacitor (CL1, CL2) : 1.0 µF or more 1.0 µF or more • 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. If the power supply suddenly increases, a momentary overshoot may be output. It is therefore important to sufficiently evaluate the output voltage at power application in the actual equipment. The application conditions for the input voltage, output voltage, and 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 7 in “ Electrical Characteristics” and footnote *5 of the table.
