Rev.2.3_00 ULTRA LOW CURRENT CONSUMPTION, HIGH RIPPLE REJECTION AND LOW DROPOUT CMOS VOLTAGE REGULATOR S-1167 Series The S-1167 Series is a positive voltage regulator with ultra low current consumption, high ripple rejection, low drop voltage and high output voltage accuracy developed based on CMOS technology. Although current consumption is very small with 9 µA typ., S-1167 Series realized the 70 dB of high ripple rejection rate. Besides a 1.0 µF ceramic capacitor is available as an input-and-output capacitor. Moreover, dropout voltage is also small since output voltage accuracy realizes ±1.0% of high accuracy, and the low-on-resistance transistor is built-in. A built-in Output current protector prevents the load current from exceeding the current capacitance of the output transistor. A shutdown circuit ensures long battery life. Two packages, SOT-23-5 and SNT-6A(H), are available. Compared with the voltage regulators using the conventional CMOS process, S-1167 Series is the most suitable for the portable equipments with ultra low current consumption and corresponding to the small package.

Check that Selection of Input Capacitor (CIN) and Output Capacitor (CL) The S-1167 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 µF or more in the entire temperature range. However, when using an OS capacitor, tantalum capacitor, or aluminum electrolytic capacitor, a ceramic capacitor with a capacitance of 1.0 µF or more and an equivalent series resistance (RESR) of 1.0 Ω or less is required. 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 value for an application is 1.0 µF or more for CIN and 1.0 µF or more for CL; however, when selecting the output capacitor, perform sufficient evaluation, including evaluation of temperature characteristics, on the actual device. 10 Seiko Instruments Inc.

Basic Operation Figure 12 shows the block diagram of the S-1167 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 output transistor with the gate voltage necessary to ensure a certain output voltage free of any fluctuations of input voltage and temperature.

Output Transistor The S-1167 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 the VOUT pin through a parasitic diode to the VIN pin. Seiko Instruments Inc. 13 ULTRA LOW CURRENT CONSUMPTION, HIGH RIPPLE REJECTION AND LOW DROPOUT CMOS VOLTAGE REGULATOR Rev.2.3_00 S-1167 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 built-in Pchannel 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 MΩ 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 product type is “A” and to the VIN pin if it is “B”.

When mounting an output capacitor between the VOUT pin and VSS pin (CL) and a capacitor for stabilizing the input between VIN pin 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 (10 µA or less). • Note that the output voltage may increase due to driver leakage when a series regulator is used at high temperatures. • 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 µF or more Output capacitor (CL) : 1.0 µF or more Equivalent series resistance (RESR) : 1.0 Ω 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. • It is important to sufficiently evaluate the output voltage fluctuation due to the power supply fluctuation and load fluctuation characteristics in the actual equipment. • If the power supply suddenly increases sharply, a momentary overshoot may be output. sufficiently evaluate the output voltage at power application in the actual equipment. It is therefore important to • 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 6 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.
