Output capacitors (CL) Generally in voltage regulator, output capacitor is used to stabilize regulation and to improve the characteristics of transient response. The S-812C Series operates stably without output capacitor CL. Thus the output capacitor CL is used only for improvement of the transient response. In the applications that users will use the S-812C Series, and they are not cautious about the transient response, it is possible to omit an output capacitor. If using an output capacitor for this IC, users are able to use devices such as ceramic capacitor which has small ESR (Equivalent Series Resistance). 2. Output voltage (VOUT) The accuracy of the output voltage 2.0% is assured under the specified conditions for input voltage, which differs depending upon the product items, output current, and temperature. Caution If the above conditions change, the output voltage value may vary and go out of the accuracy range of the output voltage. See the electrical characteristics and characteristics data for details. 3. Line regulations 1 and 2 (VOUT1, VOUT2) Indicate the dependency of the output voltage against the input voltage. That is, the value shows how much the output voltage changes due to a change in the input voltage after fixing output current constant. 4. Load regulation (VOUT3) Indicates the dependency of the output voltage against the output current. That is, the value shows how much the output voltage changes due to a change in the output current after fixing output current constant. 5. Dropout voltage (Vdrop) Indicates the difference between the output voltage and the input voltage VIN1, which is the input voltage (VIN) when; decreasing input voltage VIN gradually until the output voltage has dropped to the value of 98% of output voltage VOUT(E), which is at VIN = VOUT(S) + 1.0 V.

Basic Operation Figure 16 shows the block diagram of the S-812C Series. The error amplifier compares the reference voltage (Vref) with Vfb, which is the output voltage resistancedivided 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. VIN *1 Current supply Error amplifier - Vref VOUT Rf + Reference voltage circuit RS VSS *1. Parasitic diode Figure 16 2. Output Transistor In the S-812C 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 which flows, because of a parasitic diode between the VIN and VOUT pin. Seiko Instruments Inc. 17 HIGH OPERATING VOLTAGE CMOS VOLTAGE REGULATOR S-812C Series Rev.5.0_00 3. Power-off function (ON/OFF pin) This function starts and stops the regulator. When the ON/OFF pin is set to power-off level, the entire internal circuit stops operating, and the built-in P-channel 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 M between the VOUT and VSS pin. The ON/OFF pin is configured as shown in Figure 17 Since the ON/OFF pin is neither pulled down nor pulled up internally, do not use it in the floating state. Note that if applying the voltage of VIN + 0.3 V or more, the current flows to VIN via a parasitic diode in the IC. When not using the power-off pin in the product with the power-off function, connect the ON/OFF pin to the VIN pin (in positive logic), or to the VSS pin (in negative logic). The output voltage may increase by stopping regulation when a lower current (less than 100 A) is applied. If the output voltage increased during power-off, pull the VOUT pin down to the VSS pin and set the ON/OFF pin to the power-down level. Table 11 Logic Type ON/OFF Pin Internal Circuits VOUT Pin Voltage Current Consumption B "L": Power off Stop VSS level ISS2 B "H": Power on Operation Set value ISS VIN ON/OFF VSS Figure 17 4. Short-circuit protection circuit In the S-812C Series, users are able to select whether to set the short circuit protection, which protects the output capacitor from short-circuiting the VOUT and VSS pin. The short circuit protection circuit controls the output current against voltage VOUT, as seen in " Characteristics (Typical Data) 1", and limits the output current at approx. 40 mA even if the VOUT and VSS pins are short-circuited. However, this short circuit protection circuit does not work as for thermal protection. Pay attention to the conditions of input voltage and load current so that, under the usage condition including short circuit, the loss of the IC will not exceed power dissipation of the package. Even if pins are not short-circuited, this protection circuit works to limit the current to the specified value, in order to protect the output capacitor, when the output current and the potential difference between input and output voltages increase. In the product without the short circuit protection circuit, the S-812C Series allows the relatively larger current because this protection circuit is detached. 18 Seiko Instruments Inc. Rev.5.0_00 HIGH OPERATING VOLTAGE CMOS VOLTAGE REGULATOR S-812C Series Selection of External Components 1. Output Capacitor (CL) The S-812C Series has an internal phase compensation circuit which stabilizes the operation regardless of the change of output load. Therefore it is possible for users to have a stable operation without an output capacitor (CL). However, the values of output overshoot and undershoot, which are the characteristics of transient response, vary depending on the output capacitor. In selecting the value of output capacitor, refer to the data on CL dependency in " Reference data 1. Transient response characteristics". Set ESR 10 or less when using a tantalum capacitor or an aluminum electrolytic capacitor. Pay attention at low temperature, that aluminum electrolytic capacitor especially may oscillate because ESR increases. Evaluate sufficiently including the temperature characteristics in use. Application Circuit 1. Output Current Boost Circuit As shown in Figure 18, the output current can be boosted by externally attaching a PNP transistor. Between the input voltage VIN and the VIN pin (for power supply) in the S-812C Series, if setting the base-emitter voltage VBE which fully switches the PNP transistor on, S-812C Series controls the base current in a PNP transistor so that the output voltage VOUT reaches the level of voltage which is set by the S-812C Series. Since the output current boosting circuit in Figure 18 does not have the good characteristics of transient response, under the usage condition, confirm if output fluctuation due to power-on, and fluctuations of power supply and load affect on the operation or not before use. Note that the short-circuit protection circuit in the S-812C Series does not work as short-circuit protection for this boost circuit.

Constant Current Circuit This circuit can be used as a constant current circuit if making the composition seen in Figure 19 and 20. Constant current IO is calculated from the following equation: IO = (VOUT(E) / RL) + ISS (VOUT(E) = effective output voltage) Note that by using a circuit in Figure 19, it is impossible to set the better driving ability to the constant amperage (IO) than the S-812C Series basically has. To gain the driving ability which exceeds the S-812C Series, there's a way to combine a constant current circuit and a current boosting circuit, as seen in Figure 20. The maximum input voltage for a constant current circuit is 16 V + the voltage for device (VO). It is not recommended to add a capacitor between the VIN (power supply) and VSS pin or the VOUT (output) and VSS pin because the rush current flows at power-on.

Output Voltage Adjustment Circuit (Only for S-812CxxA Series (No short-circuit protection, power-off function)) By using the composition seen in Figure 21, users are able to increase the output voltage. The value of output voltage VOUT1 is calculated from the following equation: VOUT1 = VOUT(E) x (R1 + R2) / R1 + R2 x ISS (VOUT(E) = effective output voltage) Set the value of resistors R1 and R2 so that the S-812C Series is not affected by current consumption ISS. Capacitor C1 reduces output fluctuation due to power-on, power fluctuation and load fluctuation. Set the value according to the actual evaluation. It is not recommended to add a capacitor between the VIN (power supply) and VSS pin or the VOUT (output) and VSS pin because it causes output fluctuation and output oscillation due to power-on.

CL Rev.5.0_00 HIGH OPERATING VOLTAGE CMOS VOLTAGE REGULATOR S-812C 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 pins (CL) and a capacitor for stabilizing the input between VIN and VSS pins (CIN), the distance from the capacitors to these pins should be as short as possible. * Note that output voltage may be increased at low load current of less than 1 A. * At low load current less than 100 A output voltage may increase when the regulating operation is halted by the ON/OFF pin. * To prevent oscillation, it is recommended to use the external parts under the following conditions. Equivalent Series Resistance (ESR): 10 or less (in case of using output capacitor) Input series resistance (RIN): 10 or less * A voltage regulator may oscillate when power source impedance is high and input capacitor is low or not connected. * Pay attention to the operating conditions for input/output voltage and load current so that the power loss in the IC does not exceed the power dissipation of the package. * Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in electrostatic protection circuit. * SII claims no responsibility for any and all disputes arising out of or in connection with any infringement of the products including this IC upon patents owned by a third party.
