FOR AUTOMOTIVE 125°C OPERATION LOW DROPOUT HIGH OUTPUT CURRENT
CMOS VOLTAGE REGULATOR WITH SOFT-START FUNCTION
Rev.2.0_00
© SII Semiconductor Corporation, 2016
The S-19243xxxA Series developed by using high-withstand voltage CMOS process technology, is a positive voltage
regulator with high-accuracy output voltage and high output current.
A built-in overcurrent protection circuit to limit overcurrent of the output transistor and a built-in thermal shutdown circuit to
limit heat are included. In addition to the type in which output voltage is set inside the IC, the type for which output voltage
can be set via an external resistor is added to a lineup. Also, the S-19243xxxA Series includes the soft-start function to
adjust the output voltage rising time at power-on or at the time when the ON / OFF pin is set to ON.
Caution This product can be used in vehicle equipment and in-vehicle equipment. Before using the product in
the purpose, contact to SII Semiconductor Corporation is indispensable.

*2. The output current at which the output voltage becomes 95% of VOUT(E) after gradually increasing the output current.
*3. Vdrop = VIN1 − (VOUT3 × 0.98)
VIN1 is the input voltage at which the output voltage becomes 98% of VOUT3 after gradually decreasing the input voltage.
VOUT3 is the output voltage when VIN = VOUT(S) + 1.0 V and IOUT = 200 mA.
*4. The dropout voltage is limited by the difference between the input voltage (min. value) and the set output voltage.
In case of 1.0 V ≤ VOUT(S) < 1.5 V: 2.5 V − VOUT(S) = Vdrop
In case of 1.5 V ≤ VOUT(S) < 2.0 V: (VOUT(S) + 1.0 V) − VOUT(S) = 1.0 V
*5. Due to limitation of the power dissipation, this value may not be satisfied. Attention should be paid to the power
dissipation when the output current is large.
This specification is guaranteed by design.
*6. Soft-start time shows the time period from immediately after power-on or when the ON / OFF pin is set to ON until the
output voltage rises to 99%. Refer to "8. Soft-start function" in " Operation" for details.

 Condition of Application
Input capacitor (CIN):
Output capacitor (CL):
A ceramic capacitor with capacitance of 2.2 μF or more is recommended.
A ceramic capacitor with capacitance of 2.2 μF or more is recommended.
Caution Generally, in a voltage regulator, an oscillation may occur depending on the selection of the external
parts. Perform thorough evaluation including the temperature characteristics with an actual
application using the above capacitors to confirm no oscillation occurs.
 Selection of Input Capacitor (CIN) and Output Capacitor (CL)
The S-19243xxxA Series requires CL between the VOUT pin and the VSS pin for phase compensation. The operation
is stabilized by a ceramic capacitor with capacitance of 2.2 μF or more. When using an OS capacitor, a tantalum
capacitor or an aluminum electrolytic capacitor, the capacitance also must be 2.2 μF or more. However, an oscillation
may occur depending on the equivalent series resistance (ESR).
Moreover, the S-19243xxxA Series requires CIN between the VIN pin and the VSS pin for a stable operation.
Generally, an oscillaiton may occur when a voltage regulator is used under the conditon that the impedance of the
power supply is high.
Note that the output voltage transient characteristics varies depending on the capacitance of CIN and CL and the value
of ESR.
Caution Perform thorough evaluation including the temperature characteristics with an actual application to
select CIN and CL.
 Selection of Capacitor for Soft-start (CSS)
The S-19243xxxA Series E / F / G / H type requires the capacitor for soft-start (CSS) between the SSC pin and the
VSS pin. Over the entire temperature range, the S-19243xxxA Series operates stably with a ceramic capacitor of 0.68
nF or more. According to CSS capacitance, the rising speed of the output voltage is adjustable. The time that the
output voltage rises to 99% is 6.0 ms typ. at CSS = 10 nF. The recommended value for applications is 0.68 nF ≤ CSS ≤
168 nF, however; define the values by sufficient evaluation including the temperature characteristics under the usage
condition.
 Selection of Resistor for Output Voltage External Setting (Ra, Rb)
The S-19243xxxA Series provides the types in which output voltage can be set via the external resistor. The output
voltage can be set by connecting a resistor (Ra) between the VOUT pin and the VADJ pin, and a resistor (Rb) between
the VADJ pin and the VSS pin.
Depending on the intended output voltage, select Ra and Rb from the range shown in Table 24.
Caution Since the VADJ pin impedance is comparatively high and is easily affected by noise, pay adequate
attention to the wiring pattern.

 Operation
1.
Basic operation
Figure 28 shows the block diagram of the S-19243xxxA Series to describe the basic operation.
The error amplifier compares the feedback voltage (Vfb) whose output voltage (VOUT) is divided by the feedback
resistors (Rs and Rf) with the reference voltage (Vref). The error amplifier controls the output transistor, consequently,
the regulator starts the operation that holds VOUT constant without the influence of the input voltage (VIN).

Output transistor
In the S-19243xxxA Series, a low on-resistance P-channel MOS FET is used between the VIN pin and the VOUT
pin as the output transistor. In order to hold VOUT constant, the on-resistance of the output transistor varies
appropriately according to the output current (IOUT).
Caution Since a parasitic diode exists between the VIN pin and the VOUT pin due to the structure of the
transistor, the IC may be damaged by a reverse current if VOUT becomes higher than VIN.
Therefore, be sure that VOUT does not exceed VIN + 0.3 V.

ON / OFF pin
The ON / OFF pin controls the internal circuit and the output transistor in order to start and stop the regulator. When
the ON / OFF pin is set to OFF, the internal circuit stops operating and the output transistor between the VIN pin
and the VOUT pin is turned off, reducing current consumption significantly.
Note that the current consumption increases when a voltage of 0.6 V to VIN − 0.3 V is applied to the ON / OFF pin.
The ON / OFF pin is configured as shown in Figure 29 and Figure 30.
3. 1
S-19243xxxA Series A / C / E / G type
Since the ON / OFF pin is internally pulled down to the VSS pin in the floating status, the VOUT pin is set to the
VSS level.
Refer to " Electrical Characteristics" for the ON / OFF pin current.
3. 2
S-19243xxxA Series B / D / F / H type
Since the ON / OFF pin is neither pulled down nor pulled up, do not use these types in the floating status. When
not using the ON / OFF pin, connect it to the VIN pin.

Discharge shunt function (S-19243xxxA Series A / B / E / F type)
The S-19243xxxA Series A / B / E / F type has a built-in discharge shunt circuit to discharge the output capacitance.
The output capacitance is discharged as follows so that the VOUT pin reaches the VSS level.
(1) The ON / OFF pin is set to OFF level.
(2) The output transistor is turned off.
(3) The discharge shunt circuit is turned on.
(4) The output capacitor discharges.
Since the S-19243xxxA Series C / D / G / H type does not have a discharge shunt circuit, the VOUT pin is set to the
VSS level through several hundred kΩ internal divided resistors between the VOUT pin and the VSS pin. The
S-19243xxxA Series A / B / E / F type allows the VOUT pin to reach the VSS level rapidly due to the discharge shunt
circuit.

6.
Overcurrent protection circuit
The S-19243xxxA Series has a built-in overcurrent protection circuit to limit the overcurrent of the output transistor.
When the VOUT pin is shorted with the VSS pin, that is, at the time of the output short-circuit, the output current is
limited to 240 mA typ. due to the overcurrent protection circuit operation. The S-19243xxxA Series restarts
regulating when the output transistor is released from the overcurrent status.
Caution
7.
This overcurrent protection circuit does not work as for thermal protection. For example, when
the output transistor keeps the overcurrent status long at the time of output short-circuit or
due to other reasons, pay attention to the conditions of the input voltage and the load current
so as not to exceed the power dissipation.
Thermal shutdown circuit
The S-19243xxxA Series has a built-in thermal shutdown circuit to limit overheating. When the junction temperature
increases to 170°C typ., the thermal shutdown circuit becomes the detection status, and the regulating is stopped.
When the junction temperature decreases to 135°C typ., the thermal shutdown circuit becomes the release status,
and the regulator is restarted.
If the thermal shutdown circuit becomes the detection status due to self-heating, the regulating is stopped and VOUT
decreases. For this reason, the self-heating is limited and the temperature of the IC decreases. The thermal
shutdown circuit becomes release status when the temperature of the IC decreases, and the regulating is restarted
after the soft-start operation is finished, thus the self-heating is generated again. Repeating this procedure makes
the waveform of VOUT into a pulse-like form. This phenomenon 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. Note that the product may suffer physical damage such as deterioration if the above phenomenon
occurs continuously.
Caution
When the heat radiation of the application is not in a good condition, the self-heating cannot be
limited immediately, and the IC may suffer physical damage. Perform thorough evaluation with
an actual application to confirm no problems happen.

The S-19243xxxA Series has the built-in soft-start circuit to suppress the inrush current and overshoot of the output
voltage generated at power-on or at the time when the ON / OFF pin is set to ON. The soft-start time (tSS) is the

tSS can be adjusted by the external capacitor (CSS) connected between the SSC pin and the VSS pin, and is

*2. The delay time of internal capacitance.
When the CSS value is sufficiently large, the tD0 value can be disregarded. When the ON / OFF pin is set to OFF,
the electrical charge charged in CSS is discharged by the transistor of the discharge shunt circuit.

Types in which output voltage is externally set
The S-19243xxxA Series provides the types in which output voltage can be set via the external resistor. The output
voltage can be set by connecting a resistor (Ra) between the VOUT pin and the VADJ pin, and a resistor (Rb)
between the VADJ pin and the VSS pin.
The output voltage is determined by the following formulas.
VOUT = 1.0 + Ra × la ···················· (1)
By substituting Ia = IVADJ + 1.0 / Rb to above formula (1),
VOUT = 1.0 + Ra × (IVADJ + 1.0 / Rb) = 1.0 × (1.0 + Ra / Rb) + Ra × IVADJ ······· (2)
In above formula (2), Ra × IVADJ is a factor for the output voltage error.
Whether the output voltage error is minute is judged depending on the following (3) formula.
By substituting IVADJ = 1.0 / RVADJ to Ra × IVADJ
VOUT = 1.0 × (1.0 + Ra / Rb) + 1.0 × Ra / RVADJ ················ (3)
If RVADJ is sufficiently larger than Ra, the error is judged as minute.

 Precautions
• Generally, when a voltage regulator is used under the condition that the load current value is small (1 mA or less),
the output voltage may increase due to the leakage current of an output transistor.
• Generally, when a voltage regulator is used under the condition that the temperature is high, the output voltage may
increase due to the leakage current of an output transistor.
• Generally, when the ON / OFF pin is used under the condition of OFF, the output voltage may increase due to the
leakage current of an output transistor.
• Generally, when a voltage regulator is used under the condition that the impedance of the power supply is high, an
oscillation may occur. Perform thorough evaluation including the temperature characteristics with an actual
application to select CIN.
• Generally, in a voltage regulator, an oscillation may occur depending on the selection of the external parts. The
following use conditions are recommended in the S-19243xxxA Series; however, perform thorough evaluation
including the temperature characteristics with an actual application to select CIN and CL.
Input capacitor (CIN): A ceramic capacitor with capacitance of 2.2 μF or more is recommended.
Output capacitor (CL): A ceramic capacitor with capacitance of 2.2 μF or more is recommended.
• Generally, in a voltage regulator, the values of an overshoot and an undershoot
depending on the variation factors of input voltage start-up, input voltage fluctuation,
capacitance of CIN or CL and the value of the equivalent series resistance (ESR), which

with an actual application to
• Generally, in a voltage regulator, an overshoot may occur in the output voltage momentarily if the input voltage
steeply changes when the input voltage is started up, the soft-start operation is performed, the input voltage
fluctuates, etc. Perform thorough evaluation including the temperature characteristics with an actual application to
confirm no problems happen.
• Generally, in a voltage regulator, if the VOUT pin is steeply shorted with GND, a negative voltage exceeding the
absolute maximum ratings may occur in the VOUT pin due to resonance phenomenon of the inductance and the
capacitance including CL on the application. The resonance phenomenon is expected to be weakened by inserting a
series resistor into the resonance path, and the negative voltage is expected to be limited by inserting a protection
diode between the VOUT pin and the VSS pin.
• If the input voltage is started up steeply under the condition that the capacitance of CL is large, the thermal
shutdown circuit may be in the detection status by self-heating due to the charge current to CL.
• Make sure of the conditions for the input voltage, output voltage and the load current so that the internal loss does
not exceed the power dissipation.
• Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in electrostatic
protection circuit.
• When considering the output current value that the IC is able to output, make sure of the output current value
specified in Table 22 and Table 23 in " Electrical Characteristics" and footnote *5 of the table.
• Wiring patterns on the application related to the VIN pin, the VOUT pin and the VSS pin should be designed so that
the impedance is low. When mounting CIN between the VIN pin and the VSS pin and CL between the VOUT pin and
the VSS pin, connect the capacitors as close as possible to the respective destination pins of the IC.
• When setting the output voltage by using an external resistor, connect a resistor (Ra) between the VOUT pin and the
VADJ pin and a resistor (Rb) between the VADJ pin and the VSS pin close to the respective pins.
• In the package equipped with heat sink of backside, mount the heat sink firmly. Since the heat radiation differs
according to the condition of the application, perform thorough evaluation with an actual application to confirm no
problems happen.
• SII Semiconductor Corporation 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.
