)
: 3 kΩ 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-19311 Series requires CL between the VOUT pin and the VSS pin for phase compensation. Operation is
stabilized by a ceramic capacitor with an output capacitance of 2.2 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
2.2 μF or more, and the ESR must be 10 Ω or less.
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.
Caution Define the capacitance of CIN and CL by sufficient evaluation including the temperature
characteristics under the actual usage conditions.
Selection of Delay Time Adjustment Capacitor (CDLY
)
In the S-19311 Series, the delay time adjustment capacitor (CDLY) is necessary between the DLY pin and the VSS pin
to adjust the release delay time (trd) of the detector.
The set release delay time (trd(S)), is calculated by using following equation.
The release delay time (trd) at the time of the condition of CDLY = 47 nF is shown in " Electrical Characteristics".
C
DLY [nF]
trd(S) [ms] = trd [ms] ×
47 [nF]
Caution 1. The above equation will not guarantee successful operation. Perform thorough evaluation including
the temperature characteristics using an actual application to set the constants.
2. Mounted board layout should be made in such a way that no current flows into or flows from the DLY
pin since the impedance of the DLY pin is high, otherwise correct delay time may not be provided.
3. Select CDLY whose leakage current can be ignored against the built-in constant current. The leakage
current may cause deviation in delay time and monitoring time. When the leakage current is larger
than the built-in constant current, no release takes place.

Explanation of Terms
1. Regulator block
1. 1 Low dropout voltage regulator
This voltage regulator has the low dropout voltage due to its built-in low on-resistance transistor.
1. 2 Output voltage (VOUT
)
The accuracy of the output voltage is ensured at 2.0% 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 "1. Regulator block" in " Electrical Characteristics" and "1.
Regulator block" in " Characteristics (Typical Data)" for details.

2. Detector block
2. 1 Detection voltage (−VDET
)
The detection voltage is a voltage at which the output of the RO pin turns to "L". The detection voltage varies
slightly among products of the same specification. The variation of detection voltage between the specified
minimum (−VDET min.) and the maximum (−VDET max.) is called the detection voltage range (Refer to Figure 13).
2. 2 Release voltage (+VDET
)
The release voltage is a voltage at which the output of the RO pin turns to "H". The release voltage varies slightly
among products of the same specification. The variation of release voltage between the specified minimum (+VDET
min.) and the maximum (+VDET max.) is called the release voltage range (Refer to Figure 14). This value is
calculated from the actual detection voltage (−VDET) of a product and the hysteresis width (VHYS), and is +VDET
=
−VDET + VHYS
.

2. 3 Hysteresis width (VHYS
Figure 14 Release Voltage
)
The hysteresis width is the voltage difference between the detection voltage and the release voltage. Setting the
hysteresis width between the detection voltage and the release voltage prevents malfunction caused by noise on
the VOUT pin voltage (VOUT).
2. 4 Release delay time (trd)
The release delay time is the time period from when VOUT exceeds the release voltage (+VDET) to when the RO pin
output inverts (Refer to Figure 15), and this value changes according to the delay time adjustment capacitor
(CDLY). trd is determined by a built-in constant current which charges CDLY, the charge detection threshold of the
DLY pin, and the capacitance of CDLY. It is calculated by using the following equation.

2. 5 Reset reaction time (trr)
The reset reaction time is the time period from when VOUT falls below the detection voltage (−VDET) to when the RO
pin output inverts (Refer to Figure 16). Since trr depends on the reaction time of internal circuit and the discharge
time of CDLY, it becomes longer if the capacitance of CDLY becomes larger. Refer to "2. 9 Reset reaction time vs.

Operation
1. Regulator block
1. 1 Basic operation
Figure 17 shows the block diagram of the regulator in the S-19311 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.

1. 2 Output transistor
In the S-19311 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.

1. 3 Overcurrent protection circuit
The S-19311 Series includes an overcurrent protection circuit which having the characteristics shown in
"1. 1 Output voltage vs. Output current (When load current increases) (Ta = +25°C)" of "1. Regulator
block" in " Characteristics (Typical Data)", in order to limit an excessive output current and overcurrent of the
output transistor due to 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. 60 mA typ., and the load current when short-circuiting is limited
based on this value. The output voltage restarts regulating if the output transistor is released from overcurrent
status.
Caution This overcurrent protection circuit does not work as for thermal protection. If this IC long keeps
short circuiting, 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.
1. 4 Thermal shutdown circuit
The S-19311 Series has a thermal shutdown circuit to limit self-heating. When the junction temperature rises to
170°C typ., the thermal shutdown circuit operates to stop regulating. After that, when the junction temperature
drops to 135°C typ., the thermal shutdown circuit is released to restart regulating.
Due to self-heating of the S-19311 Series, if the thermal shutdown circuit starts operating, it stops regulating so
that the output voltage drops. For this reason, self-heating is limited and the IC's temperature drops.
When the temperature drops, the thermal shutdown circuit is released to restart regulating, thus self-heating is
generated again due to rising of the output voltage. Repeating this procedure makes the waveform of the VOUT
pin output 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.

2. Detector block
2. 1 Basic operation
(1) When the output voltage (VOUT) of the regulator is release voltage (+VDET) of the detector or higher, the Nch
transistor (N1 and N2) are turned off and "H" is output to the RO pin. Since the Pch transistor (P1) is turned on,
RB • VOUT
the input voltage to the comparator (C1) is
.
RA + RB
(2) Even if VOUT decreases to +VDET or lower, "H" is output to the RO pin when VOUT is the detection voltage (−VDET
)
or higher. When VOUT decreases to −VDET (point A in Figure 19) or lower, N1 which is controlled by C1 is turned
on, and CDLY is discharged. If the DLY pin voltage (VDLY) decreases to the lower reset timing threshold voltage
(VDRL) or lower, N2 of output stage of C2 is turned on, and then "L" is output to the RO pin. At this time, P1 is
RB • VOUT
turned off, and the input voltage to C1 is
.
RA + RB + RC
(3) If VOUT further decreases to the IC's minimum operation voltage or lower, the RO pin output is "H".
(4) When VOUT increases to the IC's minimum operation voltage or higher, "L" is output to the RO pin. Moreover,
even if VOUT exceeds −VDET, the output is "L" when VOUT is lower than +VDET
.
(5) When VOUT increases to +VDET (point B in Figure 19) or higher, N1 is turned off and CDLY is charged. N2 is
turned off if VDLY increases to the upper timing threshold voltage (VDU) or higher, and "H" is output to the RO pin.

2. 2 Delay circuit
When the output voltage (VOUT) of the regulator rises under the status that "L" is output to the RO pin, the reset
release signal is output to the RO pin later than when VOUT becomes +VDET. The release delay time (trd) changes
according to CDLY. Refer to " Selection of Delay Time Adjustment Capacitor (CDLY)" for details.
Moreover, when VOUT decreases to −VDET or lower, the delay time of the same time length as the reset reaction
time (trr) occurs in the output to the RO pin. Refer to "2. Detector block" in " Explanation of Terms" for
details.
If the time period from when VOUT decreases to −VDET or lower to when VOUT increases to +VDET or higher is
significantly shorter compared to the length of trr, VDLY may not decrease to VDRL or lower. In that case, "H" output
remains in the RO pin.
Caution Since trd depends on the charge time of CDLY, trd may be shorter than the set value if the charge
operation is initiated under the condition that a residual electric charge is left in CDLY
.
2. 3 Output circuit
The output form of the RO pin is Nch open-drain. The RO pin can output a signal without an external pull-up
resistor since it has a built-in resistor to pull up to the VOUT pin internally.
Do not connect to the pin other than VOUT pin when connecting an external pull-up resistor to the RO pin.
Caution Define the external pull-up resistance by sufficient evaluation including the temperature
characteristics under the actual usage conditions.

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 transistor 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-19311 Series. However, be sure to perform sufficient evaluation under the
actual usage conditions for selection, including evaluation of temperature characteristics. Refer to "3. 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):
2.2 μF or more
2.2 μF or more
• In a series regulator, generally the values of overshoot and undershoot in the output voltage vary depending on the
variation factors of power-on, power supply fluctuation and load fluctuation, or output capacitance.
Determine the conditions of the output capacitor after sufficiently evaluating the temperature characteristics of
overshoot or undershoot in the output voltage with the actual device.
• 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.
• 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 that time with the actual device.
• If the VOUT pin is steeply shorted with GND, a negative voltage exceeding the absolute maximum ratings may occur
to the VOUT pin due to resonance of the wiring inductance and the output capacitance in the application. The
negative voltage can be limited by inserting a protection diode between the VOUT pin and the VSS pin or inserting a
series resistor to the output capacitor.
• The application conditions for the input voltage, the output voltage, and the load current should 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.
• 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.
• 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.
