Rev.1.3_00
The S-1142C/D Series, developed by using high-withstand voltage CMOS technology, is a positive voltage regulator
with a high-withstand voltage, low current consumption, and high-accuracy output voltage.
The S-1142C/D Series operates at a high maximum operating voltage of 50 V and a low current consumption of 4.0 μA
typ. In addition to a built-in low on-resistance transistor which provides a very small dropout voltage and a large output
current, this voltage regulator also has a built-in ON / OFF circuit.
An 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 heat.
A high heat radiation HSOP-6 package enables high-density mounting.

Caution The above connection diagram and constants will not guarantee successful operation. Perform
thorough evaluation using an actual application to set the constants.
Condition of Application
Input capacitor (CIN):
0.1 μF or more
Output capacitor (CL): 0.1 μF or more
Caution 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-1142C/D 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 0.1 μF or more over the entire
temperature range. When using an OS capacitor, a tantalum capacitor, or an aluminum electrolytic capacitor, the
capacitance must be 0.1 μF or more.
The values of output overshoot and undershoot, which are transient response characteristics, vary depending on the
value of the 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 ≥ 0.1 μF
CL ≥ 0.1 μF
Caution Define the capacitance of CIN and CL by sufficient evaluation including the temperature
characteristics under the actual usage conditions.

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. Output voltage (VOUT
)
The accuracy of the output voltage is ensured at 3.0% under 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 " Electrical Characteristics" and " Characteristics
(Typical Data)" for details.
ΔVOUT1
ΔVIN • VOUT
3. Line regulation
Indicates the dependency of the output voltage against the input voltage. That is, the value shows how much the
output voltage changes due to a change in the input voltage after fixing output current constant.
4. Load regulation (ΔVOUT2
)
Indicates the dependency of the output voltage against the output current. That is, the value shows how much the
output voltage changes due to a change in the output current after fixing input voltage constant.
5. Dropout voltage (Vdrop
)
Indicates the difference between input voltage (VIN1) and the output voltage when; decreasing input voltage (VIN)
gradually until the output voltage has dropped out to the value of 98% of output voltage (VOUT3), which is at VIN
=
VOUT(S) + 2.0 V.

Operation
1. Basic operation
Figure 11 shows the block diagram of the S-1142C/D 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-1142C/D 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.
13

S-1142C/D Series
Rev.1.3_00
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 MΩ between the
VOUT pin and the VSS pin.
Note that the current consumption increases when a voltage of 0.3 V to VIN − 0.3 V is applied to the ON / OFF
pin.
The ON / OFF pin is configured 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 status. When not using the ON / OFF pin, connect it to the VSS pin in
the product C type, and connect it to the VIN pin in the D type.

4. Overcurrent protection circuit
The S-1142C/D Series includes an overcurrent protection circuit having the characteristics shown in "1. Output
voltage vs. Output current (When load current increases) (Ta = +25°C)" 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.
80 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.

5. Thermal shutdown circuit
The S-1142C/D Series has a thermal shutdown circuit to protect the device from damage due to overheat. When
the junction temperature rises to 150°C typ., the thermal shutdown circuit operates to stop regulating. When the
junction temperature drops to 125°C typ., the thermal shutdown circuit is released to restart regulating.
Due to self-heating of the S-1142C/D Series, if the thermal shutdown circuit starts operating, it stops regulating
so that the output voltage drops. When regulation stops, the S-1142C/D Series does not itself generate heat and
the IC’s temperature drops. When the temperature drops, the thermal shutdown circuit is released to restart
regulating, thus this IC generates heat again. Repeating this procedure makes the waveform of the output voltage
into a 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. Overshoot of output voltage
Overshoot of output voltage occurs depending on the condition such as the rising speed of input voltage (VIN).
Overshoot voltage is the difference between the maximum value of output voltage generated by the fluctuation of
V
IN and the actual output voltage (VOUT(E)) value.
6. 1 At normal operation
As shown in Figure 13, Vgs is the voltage difference between VIN and gate voltage of output driver.
The error amplifier controls Vgs in order to keep the output voltage constant depending on the fluctuation of VIN
and the output load.

6. 2 Occurrence of overshoot
If VIN voltage rises at a fast speed, Vgs may become large when gate voltage of output driver can not follow the
speed of VIN. When Vgs becomes large, the current supplied from output driver is increased transiently. Thereby,
output voltage rises, and then overshoot occurs.
Note that overshoot voltage is greatly affected by the following use conditions or temperature, etc.
• When VIN rises in the range of 2.0 V to VOUT(E)
• When the rising speed of VIN is fast.
• When the output capacitance is small.
• When the output load is small.

Caution Under the following conditions, overshoot voltage tends to become larger especially.
• When VIN rises from around 98% of VOUT(E)
• When the rising speed of VIN is 200 mV/μs or more.

S-1142C/D Series
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 (0.1 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-1142C/D Series. However, be sure to perform sufficient evaluation under
the actual usage conditions for selection, including evaluation of temperature characteristics. Refer to "6.
Example of equivalent series resistance vs. Output current characteristics (Ta = +25°C)" in " Reference
Data" for the equivalent series resistance (RESR) of the output capacitor.
Input capacitor (CIN):
Output capacitor (CL):
0.1 μF or more
0.1 μF 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.
• Sufficiently evaluate the output voltage fluctuations caused by the power supply or the load fluctuations 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 *4 of the table.
• ABLIC Inc. claims no responsibility for any disputes arising out of or in connection with any infringement by
products including this IC of patents owned by a third party.
