ULTRA LOW CURRENT CONSUMPTION, HIGH RIPPLE
AND LOW DROPOUT CMOS VOLTAGE REGULATOR
REJECTION
S-1167
Series
www.datasheet4u.com
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.

Technical Terms
1. Low Dropout Voltage Regulator
www.datasheeTth4ue.cloomw dropout voltage regulator is a voltage regulator whose dropout voltage is low due to its built-in low on-
resistance 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.
*1. Differs depending on the product.
Caution If the above conditions change, the output voltage value may vary and exceed the accuracy range
of the output voltage. Refer to the “Electrical Characteristics” and “Typical Characteristics” for
details.
4. Line Regulation
∆VOUT1
∆VIN • VOUT
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 × 0.98).
Vdrop = VIN1 − (VOUT3 × 0.98)
