S-1323 Series www.sii-ic.com HIGH RIPPLE-REJECTION AND SMALL PACKAGE CMOS VOLTAGE REGULATOR Rev.5.0_00 (c) Seiko Instruments Inc., 2002-2010 The S-1323 Series is a positive voltage regulator with a low dropout voltage, high output voltage accuracy, and low current consumption developed based on CMOS technology. A built-in low on-resistance transistor provides a low dropout voltage and large output current, and a built-in overcurrent protector prevents the load current from exceeding the current capacitance of the output transistor. An ON/OFF circuit ensures a long battery life. Compared with the voltage regulators using the conventional CMOS process, a larger variety of capacitors are available, including small ceramic capacitors. Small SNT-4A and SC-82AB packages realize high-density mounting.

Seiko Instruments Inc. 9 HIGH RIPPLE-REJECTION AND SMALL PACKAGE CMOS VOLTAGE REGULATOR Rev.5.0_00 S-1323 Series Explanation of Terms 1. Low dropout voltage regulator The low dropout voltage regulator is a voltage regulator whose dropout voltage is low due to its built-in low on-resistance transistor. 2. Low ESR A capacitor whose ESR (Equivalent Series Resistance) is low. The S-1323 Series enables use of a low ESR capacitor, such as a ceramic capacitor, for the output-side capacitor CL. A capacitor whose ESR is 10 or less can be used. 3. 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 the product. Caution If the above conditions change, the output voltage value may vary and exceed the accuracy range of the output voltage. Please see the electrical characteristics and attached characteristics data for details. 4. Line regulation V OUT1 V IN * V OUT Indicates the dependency of the output voltage on the input voltage. That is, the values show how much the output voltage changes due to a change in the input voltage with the output current remaining unchanged. 5. Load regulation (VOUT2) Indicates the dependency of the output voltage on the output current. That is, the values show how much the output voltage changes due to a change in the output current with the input voltage remaining unchanged. 6. Dropout voltage (Vdrop) Indicates the difference between the input voltage VIN1, which is the input voltage (VIN) at the point where the output voltage has fallen to 98% of the output voltage value VOUT3 after VIN was gradually decreased from VIN = VOUT(S) + 1.0 V, and the output voltage at that point (VOUT3 x 0.98).

Basic operation Figure 12 shows the block diagram of the S-1323 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 output transistor with the gate voltage necessary to ensure a certain output voltage free of any fluctuations of input voltage and temperature. VIN *1 Current supply Error amplifier VOUT Vref - Rf + Vfb Reference voltage circuit Rs VSS *1. Parasitic diode Figure 12 2. Output transistor The S-1323 Series uses a low on-resistance P-channel MOS FET 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 VOUT pin through a parasitic diode to VIN pin. 12 Seiko Instruments Inc. Rev.5.0_00 HIGH RIPPLE-REJECTION AND SMALL PACKAGE CMOS VOLTAGE REGULATOR S-1323 Series 3. Shutdown pin (ON/OFF pin) This pin starts and stops the regulator. When the ON/OFF pin is set to the shutdown level, the operation of all internal circuits stops, and the builtin P-channel MOS FET output transistor between the VIN pin and VOUT pin is turned off to substantially reduce the current consumption. The VOUT pin becomes the VSS level due to the internally divided resistance of several hundreds k between the VOUT pin and VSS pin. The structure of the ON/OFF pin is as shown in Figure 13. Since the ON/OFF pin is neither pulled down nor pulled up internally, do not use it in the floating state. In addition, note that the current consumption increases if a voltage of 0.3 V to VIN - 0.3 V is applied to the ON/OFF pin. When the ON/OFF pin is not used, connect it to the VSS pin if the logic type is "A" and to the VIN pin if it is "B". Table 6 Logic Type ON/OFF Pin Internal Circuits VOUT Pin Voltage Current Consumption A "L": Power on Operating Set value ISS1 A "H": Power off Stopped VSS level ISS2 B "L": Power off Stopped VSS level ISS2 B "H": Power on Operating Set value ISS1 VIN ON/OFF VSS Figure 13 Selection of Output Capacitor (CL) The S-1323 Series requires an output capacitor between the VOUT and VSS pins for phase compensation. A ceramic capacitor with a capacitance of 1.0 F or more can be used. Even if using an OS capacitor, tantalum capacitor, or aluminum electrolytic capacitor, a capacitance of 1.0 F or more and an ESR of 10 or less are required. The value of the output overshoot or undershoot transient response varies depending on the value of the output capacitor. When selecting the output capacitor, perform sufficient evaluation, including evaluation of temperature characteristics, on the actual device. Seiko Instruments Inc. 13 HIGH RIPPLE-REJECTION AND SMALL PACKAGE CMOS VOLTAGE REGULATOR Rev.5.0_00 S-1323 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 the output voltage may increase when a series regulator is used at low load current (1.0 mA or less). * 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. Input capacitor (CIN): 1.0 F or more Output capacitor (CL): 1.0 F or more Equivalent series resistance (ESR): 10 or less * 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. * 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 5 in the electrical characteristics and footnote *5 of the table. * SII claims no responsibility for any disputes arising out of or in connection with any infringement by products including this IC of patents owned by a third party. 14 Seiko Instruments Inc.
