HIGH RIPPLE-REJECTION  
LOW DROPOUT CMOS VOLTAGE REGULATOR  
S-1165 Series  
The S-1165 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, and a small SOT-23-5 package  
realizes high-density mounting.  
„ Features  
1.5 V to 5.5 V, selectable in 0.1 V steps.  
High-accuracy output voltage: ±1.0%  
Output voltage:  
Low dropout voltage:  
140 mV typ. (3.0 V output product, IOUT = 200 mA)  
During operation: 35 μA typ., 65 μA max.  
During shutdown: 0.1 μA typ., 1.0 μA max.  
High peak current capability: 200 mA output is possible (at VIN VOUT(S) + 1.0 V)*1  
Low current consumption:  
Ensures long battery life.  
70 dB typ. (at 1.0 kHz)  
Overcurrent of output transistor can be restricted.

Built-in ON/OFF circuit:  
High ripple rejection:  
Built-in overcurrent protector:  
Small package:  
Lead-free products  
*1. Attention should be paid to the power dissipation of the package when the output current is large.

„ 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. 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.

ΔVIN VOUT  
3. Line regulation  
Indicates the dependency of the output voltage on the input voltage. That is, the value shows how much  
the output voltage changes due to a change in the input voltage with the output current remaining  
unchanged.  
4. Load regulation (ΔVOUT2  
)
Indicates the dependency of the output voltage on the output current. That is, the value shows how  
much the output voltage changes due to a change in the output current with the input voltage remaining  
unchanged.  
5. 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)

„ Operation  
1. Basic operation  
Figure 11 shows the block diagram of the S-1165 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-1165 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.

Rev.3.1_00  
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 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 kΩ between the VOUT pin and VSS pin.  
The structure of the ON/OFF pin is as shown in Figure 12. 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”.

„ Selection of Output Capacitor (CL)  
The S-1165 Series performs phase compensation using the internal phase compensator in the IC and the ESR  
(Equivalent Series Resistance) of the output capacitor to enable stable operation independent of changes in the  
output load. Therefore, always place a capacitor (CL) of 2.2 μF or more between VOUT and VSS pins.  
For stable operation of the S-1165 Series, it is essential to employ a capacitor whose ESR is within an optimum  
range. Using a capacitor whose ESR is outside the optimum range (approximately 0.5 to 5 Ω), whether larger  
or smaller, may cause an unstable output, resulting in oscillation. For this reason, a tantalum electrolytic  
capacitor is recommended.  
When a ceramic capacitor or an OS capacitor with a low ESR is used, it is necessary to connect an additional  
resistor that serves as the ESR in series with the output capacitor. The required resistance value is  
approximately 0.5 to 5 Ω, which varies depending on the usage conditions, so perform sufficient evaluation for  
selection. Ordinarily, around 1.0 Ω is recommended.  
Note that an aluminum electrolytic capacitor may increase the ESR at a low temperature, causing oscillation.  
When using this kind of capacitor, perform thorough evaluation, including evaluation of temperature  
characteristics.

„ 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).  
This IC performs phase compensation by using an internal phase compensator and the ESR of an  
output capacitor. Therefore, always place a capacitor of 2.2 μF or more between VOUT and VSS pins.  
A tantalum type capacitor is recommended. Moreover, to secure stable operation of the S-1165 Series,  
it is necessary to employ a capacitor with an ESR within an optimum range (0.5 to 5 Ω). Using a  
capacitor whose ESR is outside the optimum range (approximately 0.5 to 5 Ω), whether larger or  
smaller, may cause an unstable output, resulting in oscillation. Perform sufficient evaluation under the  
actual usage conditions for selection, including evaluation of temperature characteristics.  
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  
4 in the electrical characteristics and footnote *5) of the table.
