HIGH RIPPLE-REJECTION AND SMALL PACKAGE  
CMOS VOLTAGE REGULATOR  
S-1323 Series  
The S-1323 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. Compared with the voltage regulators using the  
conventional CMOS process, a larger variety of  
capacitors are available, including small ceramic  
capacitors. Small SNT-4A and SC-82AB packages  
realize high-density mounting.  
„ Features  
1.5 V to 5.5 V, selectable in 0.1 V steps.  
Output voltage:  
High-accuracy output voltage:  
Low current consumption:  
1.0%  
During operation: 70 µA typ., 90 µA max.  
During shutdown: 0.1 µA typ., 1.0 µA max.  
150 mA output is possible (at VIN VOUT(S) + 1.0 V)*1  
Ensures long battery life.  
High peak current capability:  
Built-in ON/OFF circuit:  
Low ESR capacitor can be used: A ceramic capacitor of 1.0 µF or more can be used for the output  
capacitor.  
70 dB typ. (at 1.0 kHz)  
High ripple rejection:  
Built-in overcurrent protector:  
Small package:  
Overcurrent of output transistor can be restricted.  
SNT-4A, SC-82AB  
Lead-free products  
*1. Attention should be paid to the power dissipation of the package when the output current is large.  
„ Applications  
Power supply for battery-powered devices  
Power supply for personal communication devices  
Power supply for home electric/electronic appliances  
Power supply for cellular phones

„ 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. Low ESR  
A capacitor whose ESR (Equivalent Series Resistance) is low. The S-1323 Series enables use of a low  
ESR capacitor, such as a ceramic capacitor, for the output-side capacitor CL. A capacitor whose ESR is  
10 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. Please see the electrical characteristics and  
attached characteristics data for details.

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)

„ Operation  
1. Basic operation  
Figure 12 shows the block diagram of the S-1323 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.

Figure 12  
2. Output transistor  
The S-1323 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.

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 kbetween 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 logic type is “A” and to the VIN pin if it is “B”.

„ Selection of Output Capacitor (CL)  
The S-1323 Series requires an output capacitor between the VOUT and VSS pins for phase compensation. A  
ceramic capacitor with a capacitance of 1.0 µF or more can be used. Even if using an OS capacitor, tantalum  
capacitor, or aluminum electrolytic capacitor, a capacitance of 1.0 µF or more and an ESR of 10 or less are  
required.  
The value of the output overshoot or undershoot transient response varies depending on the value of the output  
capacitor.  
When selecting the output capacitor, perform sufficient evaluation, including evaluation of temperature  
characteristics, on the actual device.

„ 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).  
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):  
Output capacitor (CL):  
1.0 µF or more  
1.0 µF or more  
Equivalent series resistance (ESR): 10 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.  
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  
5 in the electrical characteristics and footnote *5 of the table.
