Rev.4.1_02
The S-1170 Series is a positive voltage regulator with a low dropout voltage, high-accuracy output voltage, 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, a built-in
overcurrent protection circuit prevents the load current from exceeding the current capacity of the output
transistor, and a built-in thermal shutdown circuit prevents damage caused by the heat. An ON/OFF circuit
ensures a long battery life. Compared with the voltage regulators using the conventional CMOS technology, a
larger variety of capacitors are available, including small ceramic capacitors. Small SOT-89-5 and 6-Pin
HSON(A) packages realize high-density mounting.

Caution The above connection diagram and constant will not guarantee successful operation.
Perform thorough evaluation using the actual application to set the constant.
Condition of Application
Input capacitor (CIN):
Output capacitor (CL):
ESR of output capacitor:
4.7 F or more
4.7 F or more
0.5 or less
Caution Generally a series regulator may cause oscillation, depending on the selection of external
parts. Check that no oscillation occurs with the application using the above capacitor.
Selection of Input and Output Capacitors (CIN, CL)
The S-1170 Series requires an output capacitor between the VOUT pin and the VSS pin for phase
compensation. A ceramic capacitor with a capacitance of 4.7 F or more provides a stable operation in all
temperature ranges. When using an OS capacitor, a tantalum capacitor, or an aluminum electrolytic
capacitor, the capacitance must be 4.7 F or more, and the ESR must be 0.5 or less.
The output overshoot and undershoot values, which are transient response characteristics, vary depending
on the output capacitor value. The required capacitance value for the input capacitor differs depending on
the application.
The recommended value for an application is CIN 4.7 F and CL 4.7 F, however, perform a thorough
evaluation using the actual device, including evaluation of temperature characteristics.

Explanation of Terms
1. Low dropout voltage regulator
This voltage regulator has the low dropout voltage due to its built-in low on-resistance transistor.
2. Low ESR
A capacitor whose ESR (Equivalent Series Resistance) is low. The S-1170 Series enables use of a low
ESR capacitor, such as a ceramic capacitor, for the output-side capacitor (CL). A capacitor whose ESR
is 0.5 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. Refer to “ Electrical Characteristics” and “
Characteristics (Typical Data)” for details.

Operation
1. Basic operation
Figure 12 shows the block diagram of the S-1170 Series.
The error amplifier compares the reference voltage (Vref) with feedback voltage (Vfb), which is the output
voltage resistance-divided 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.

2. Output transistor
In the S-1170 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 reverse current flowing from the VOUT pin through a parasitic diode to the VIN pin, when the potential
of VOUT became higher than VIN.

Rev.4.1_02
S-1170 Series
3. ON/OFF pin
This pin starts and stops the regulator.
When the ON/OFF pin is set to OFF level, the entire internal circuit stops operating, and the built-in
P-channel MOS FET output transistor between the VIN pin and the VOUT pin is turned off, reducing
current consumption significantly. The VOUT pin becomes the VSS level due to the internally divided
resistance of several hundreds k between the VOUT pin and the 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 status. 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 not using the ON/OFF
pin, connect it to the VSS pin in the product A type, and connect it to the VIN pin in B type.

S-1170 Series
4. Thermal shutdown circuit
The S-1170 Series implements a thermal shutdown circuit to protect the device from damage due to
overheating. When the junction temperature rises to 150C (typ.), the thermal shutdown circuit operates
and the regulator operation stops. When the junction temperature drops to 120C (typ.), the thermal
shutdown circuit is released and the regulator operation resumes.
If the thermal shutdown circuit starts operating due to self-heating, the regulator operation stops and the
output voltage falls. When the regulator operation has stopped, no self-heat is generated and the
temperature of the IC is lowered. When the temperature has dropped, the thermal shutdown circuit is
released, the regulator operation resumes, and self-heat is generated again. By repeating this procedure,
the output voltage waveform forms pulses. Stop or restart of regulation continues unless decreasing
either or both of the input voltage and the output current in order to reduce the internal power
consumption, or decreasing the ambient temperature.

Precautions
Wiring patterns for the VIN pin, the VOUT pin and GND should be designed so that the impedance is
low. When mounting an output capacitor between the VOUT pin and the VSS pin (CL) and a capacitor
for stabilizing the input between the VIN pin and the VSS pin (CIN), the distance from the capacitors to
these pins should be as short as possible.
Note that generally the output voltage may increase when a series regulator is used at low load current
(1.0 mA or less).
Note that the output voltage may increase due to the leakage current from an output driver even if the
ON/OFF pin is at OFF level when a series regulator is used at high temperature.
Generally a series regulator may cause oscillation, depending on the selection of external parts. The
following conditions are recommended for the S-1170 Series. However, be sure to perform sufficient
evaluation under the actual usage conditions for selection, including evaluation of temperature
characteristics.
Input capacitor (CIN):
Output capacitor (CL):
4.7 F or more
4.7 F or more
Equivalent series resistance (ESR): 0.5 or less
The voltage regulator may oscillate when the impedance of the power supply is high and the input
capacitance is small or an input capacitor is not connected.
Overshoot may occur in the output voltage momentarily if the voltage is rapidly raised at power-on or
when the power supply fluctuates. Sufficiently evaluate the output voltage at power-on with the actual
device.
The application conditions for the input voltage, the output voltage, and the 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 “ Electrical Characteristics” and footnote *5 of the table.

by products including this IC of patents owned by a third party.
