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.

„ 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.

„ Technical 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 onresistance transistor.
2. Low Equivalent Series Resistance
A capacitor whose equivalent series resistance (RESR) is low. The S-1167 Series enables use of a low equivalent
series resistance capacitor, such as a ceramic capacitor, for the output-side capacitor (CL). A capacitor whose RESR
is 1.0 Ω 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.

„ Operation
1. 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.

2. 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.

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”.

„ Precautions
• Wiring patterns for the VIN pin, VOUT pin and GND pin should be designed so that the impedance is low. 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.
