HIGH OUTPUT CURRENT CMOS VOLTAGE REGULATOR

Rev.2.2_03  
The S-1172 Series, developed by using CMOS technology, is a positive voltage regulator with a super low dropout voltage,  
high-accuracy output voltage and low current consumption.  
The S-1172 Series provides the very low dropout voltage and the large output current due to the built-in transistor with low  
on-resistance. The S-1172 Series includes an overcurrent protection circuit that prevents the load current from exceeding  
the current capacitance of the output transistor, a thermal shutdown circuit that prevents damage due to overheating, and  
an inrush current limit circuit to limit the excessive inrush current generated at power-on.  
The ON/OFF circuit ensures longer battery life. Compared with the voltage regulators using the conventional CMOS  
technology, a large variety of capacitors are available, including small ceramic capacitors.  
High heat radiation HSOP-6 and small SOT-89-5 packages realize high-density mounting.

2. Generally a series regulator may cause oscillation, depending on the selection of external  
parts. Confirm that no oscillation occurs in the application for which the above capacitors are  
used.  
Selection of Input and Output Capacitors (CIN, CL)  
The S-1172 Series requires an output capacitor between the VOUT pin and the VSS pin for phase compensation.  
Operation is stabilized by a ceramic capacitor with an output capacitance of 4.7 F or more over the entire  
temperature range. When using an OS capacitor, a tantalum capacitor, or an aluminum electrolytic capacitor, the  
capacitance must be 4.7 F or more.  
The values of output overshoot and undershoot, which are transient response characteristics, vary depending on the  
value of output capacitor.  
The required value of capacitance for the input capacitor differs depending on the application.  
Set the value for input capacitor (CIN) and output capacitor (CL) as follows.  
CIN 4.7 F  
CL 4.7 F  
CIN = CL  
Caution The S-1172 Series may oscillate if setting the value as CIN 4.7 F, CL 4.7 F, CIN CL.  
Define the values by sufficient evaluation including the temperature characteristics under the usage  
condition.

Operation  
1. Basic operation  
Figure 13 shows the block diagram of the S-1172 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-1172 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.2.2_03  
S-1172 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 is set to the VSS level by the internal dividing resistor of several hundred kbetween  
the VOUT pin and the VSS pin.  
Note that the current consumption increases when a voltage of 0.3 V to 1.0 V is applied to the ON/OFF pin.  
The ON/OFF pin is configured as shown in Figure 14. Since the ON/OFF pin is neither pulled down nor pulled up  
internally, do not use it in the floating status. 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.

4. Overcurrent protection circuit  
The S-1172 Series includes an overcurrent protection circuit having the characteristics shown in “1. Output  
voltage vs. Output current (When load current increases) (Ta = 25C)” in “Characteristics (Typical Data)”,  
in order to protect the output transistor against an excessive output current and short circuiting between the VOUT  
pin and the VSS pin. The current when the output pin is short-circuited (ISHORT) is internally set at approx. 200 mA  
typ., and the normal value is restored for the output voltage, if releasing a short circuit once.  
Caution This overcurrent protection circuit does not work as for thermal protection. If this IC long keeps  
short circuiting inside, pay attention to the conditions of input voltage and load current so that,  
under the usage conditions including short circuit, the loss of the IC will not exceed power  
dissipation of the package.

S-1172 Series  
Rev.2.2_03  
5. Thermal shutdown circuit  
The S-1172 Series has a thermal shutdown circuit to protect the device from damage due to overheat. When the  
junction temperature rises to 150C typ., the thermal shutdown circuit operates to stop regulating. When the  
junction temperature drops to 120C typ., the thermal shutdown circuit is released to restart regulating.  
Due to self-heating of the S-1172 Series, if the thermal shutdown circuit starts operating, it stops regulating so that  
the output voltage drops. When regulation stops, the S-1172 Series does not itself generate heat so that the IC’s  
temperature drops. When the temperature drops, the thermal shutdown circuit is released to restart regulating, thus  
the S-1172 Series generates heat again. Repeating this procedure makes waveform of the output voltage pulse-like  
form. 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.

6. Inrush current limit circuit  
The S-1172 Series has a built-in inrush current limit circuit to limit the inrush current generated at power-on or at  
the time when the ON/OFF pin is set to ON. This circuit limits the inrush current (500 mA, typ.) immediately after  
power-on or from the time when the ON/OFF pin is set to ON until the specified time (100 s min.) which is set  
internally.  
Caution The junction temperature drops to 120C typ. by the operation of thermal shutdown circuit, after  
stopping regulation, the circuit is released to restart regulation; in this case, note that the period  
to limit inrush current may become shorter (10 s min.).

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 generally the output voltage may increase due to the leakage current from an output driver when a series  
regulator is used at high temperature.  
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-1172 Series. However, be sure to perform sufficient evaluation under the  
actual usage conditions for selection, including evaluation of temperature characteristics. Refer to “5. Example of  
equivalent series resistance vs. Output current characteristics (Ta = 25C)” in “Reference Data” for the  
equivalent series resistance (RESR) of the output capacitor.  
Input capacitor (CIN):  
Output capacitor (CL):  
4.7 F or more  
4.7 F or more  
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. Note that the voltage regulator may oscillate when the value of the  
output capacitor is greater than that of the input capacitor.  
Ringing may occur when these three conditions below are satisfied. Before selecting an input capacitor, be sure to  
evaluate sufficiently under the actual usage conditions, including the temperature characteristics.  
The power supply inductance is high.  
The load current is 100 mA or more.  
The difference between the input voltage and the output voltage is close to the value of dropout voltage.  
If the output capacitance is small, power supply’s fluctuation and the characteristics of load fluctuation become worse.  
Sufficiently evaluate the output voltage’s fluctuation with the actual device.  
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 7 in  
Electrical Characteristics” and footnote *5 of the table.
