WITH SENSE-INPUT RESET FUNCTION
Rev.1.1_01
© ABLIC Inc., 2020
The S-19315 Series, developed by using high-withstand voltage CMOS process technology, is a positive voltage regulator
with the reset function, which has high-withstand voltage and low current consumption.
Apart from the power supply pin, the detection voltage input pin (SENSE pin) is also prepared for the reset function, so the
output is stable even if the SENSE pin falls to 0 V. The output form is Nch open-drain output.

Condition of Application
Input capacitor (CIN):
Output capacitor (CL):
A ceramic capacitor with capacitance of 1.0 μF or more is recommended.
A ceramic capacitor with capacitance of 1.0 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-19315 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 1.0 μF or more. When using an OS capacitor, a
tantalum capacitor or an aluminum electrolytic capacitor, the capacitance also must be 1.0 μF or more. However, an
oscillation may occur depending on the equivalent series resistance (ESR).
Moreover, the S-19315 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 (VOUT) 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.

1. 1
Low dropout voltage regulator
This is a voltage regulator which made dropout voltage small by its built-in low on-resistance output transistor.
1. 2
Output voltage (VOUT)
This voltage is output at an accuracy of ±2.0% or ±0.03 V*2 when the input voltage, the output current and the
temperature are in a certain condition*1.
*1. Differs depending on the product.
*2. When VOUT < 1.5 V: ±0.03 V, when VOUT ≥ 1.5 V: ±2.0%
Caution If the certain condition is not satisfied, the output voltage may exceed the accuracy range of
±2.0% or ±0.03 V. Refer to "1. Regulator block" in " Electrical Characteristics" and "1.
Regulator block" in " Characteristics (Typical Data)" for details.
1. 3
Line regulation
ΔVOUT1
ΔVIN • VOUT
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.
1. 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.
1. 5
Dropout voltage (Vdrop)
Indicates the difference between input voltage (VIN1) and the output voltage when the output voltage becomes
98% of the output voltage value (VOUT3) at VIN = 4.0 V (1.0 V ≤ VOUT(S) < 2.0 V) or VIN = VOUT(S) + 2.0 V (2.0 V ≤
VOUT(S) ≤ 5.3 V) after the input voltage (VIN) is decreased gradually.
Vdrop = VIN1 − (VOUT3 × 0.98)

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 14).
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 15).

Operation

Regulator block
1. 1
Basic operation
Figure 16 shows the block diagram of the regulator block 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 keeps VOUT constant without the influence of
the input voltage (VIN).

Output transistor
In the S-19315 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 keep 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 circuit
The ON / OFF circuit controls the internal circuit and the output transistor in order to start and stop the regulator.
When the detector becomes the detection status, the internal circuit of regulator stops operating and the output
transistor between the VIN pin and the VOUT pin is turned off, reducing current consumption significantly.

Overcurrent protection circuit
The S-19315 Series has a built-in overcurrent protection circuit to limit the overcurrent of the output transistor.
When the VOUT pin is shorted to the VSS pin, that is, at the time of the output short-circuit, the output current is
limited to 24 mA typ. due to the overcurrent protection circuit operation. The S-19315 Series restarts regulating
when the output transistor is released from the overcurrent status.
Caution 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.
1. 6
Thermal shutdown circuit
The S-19315 Series has a built-in thermal shutdown circuit to limit overheating. When the junction temperature
increases to 160°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 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
If a large load current flows during the restart process of regulating after the thermal shutdown
circuit changes to the release status from the detection status, the thermal shutdown circuit
becomes the detection status again due to self-heating, and a problem may happen in the
restart of regulating. A large load current, for example, occurs when charging to the CL whose
capacitance is large.
Perform thorough evaluation including the temperature characteristics with an actual
application to select CL.

the release voltage (+VDET) or higher, the Nch transistor (N1) is off, and the RO pin output is "H".

Since the Nch transistor (N2) is off, the input voltage to the comparator is

(2) Even if VSENSE decreases to +VDET or lower, the RO pin output is "H" when VSENSE is the detection voltage
(−VDET) or higher. When VSENSE is −VDET (point A in Figure 19) or lower, N1 is on, and the RO pin output is "L".

At this time, N2 is turned on, and the input voltage to the comparator is

(3) Even if VSENSE further decreases to the IC's minimum operation voltage or lower, the RO pin output is stable
when VIN is the minimum operation voltage or higher.
(4) Even if VSENSE exceeds −VDET, the RO pin output is "L" when VSENSE is lower than +VDET.

Error when detection voltage is set externally
By connecting a node that was resistance-divided by the resistor (RA) and the resistor (RB) to the SENSE pin as
seen in Figure 20, the detection voltage can be set externally. Although the internal resistance (RSENSE) in the
S-19315 Series is large (13 MΩ min.) to make the error in the current flowing through RSENSE small, RA and RB
should be selected such that the error is within the allowable limits.
If the VSENSE greatly exceeds the +VDET, the current flowing through RSENSE is limited.
2. 2. 2
Selection of RA and RB
In Figure 20, the relation between the external setting detection voltage (VDX) and the actual detection voltage
(−VDET) is ideally calculated by the equation below.
VDX = −VDET ×
(1 +
RA
RB )
··· (1)
However, in reality there is an error in the current flowing through RSENSE.
When considering this error, the relation between VDX and −VDET is calculated as follows.

By using equations (1) and (2), the error is calculated as −VDET × R

The error rate is calculated as follows by dividing the error by the right-hand side of equation (1).

··· (3)
As seen in equation (3), the smaller the resistance values of RA and RB compared to RSENSE, the smaller the error
rate becomes.
Also, the relation between the external setting hysteresis width (VHX) and the hysteresis width (VHYS) is calculated
by equation below. Error due to RSENSE also occurs to the relation in a similar way to the detection voltage.

Caution 1. If RA and RB are large, the SENSE pin input impedance becomes higher and may cause a

2. If the parasitic resistance and parasitic inductance between VDX and point A and between point
A and VIN pin are respectively larger, oscillation may occur. Perform thorough evaluation
using the actual application.

Precautions
•
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-19315 Series; however, perform thorough evaluation including
the temperature characteristics with an actual application to select CIN and CL.
Input capacitor (CIN):
Output capacitor (CL):
A ceramic capacitor with capacitance of 1.0 μF or more is recommended.
A ceramic capacitor with capacitance of 1.0 μF or more is recommended.
•
Generally, in a voltage regulator, the values of an overshoot and an undershoot in the output voltage vary
depending on the variation factors of input voltage start-up, input voltage fluctuation, load fluctuation etc., or the
capacitance of CIN or CL and the value of the equivalent series resistance (ESR), which may cause a problem to the
stable operation. Perform thorough evaluation including the temperature characteristics with an actual application to
select CIN and CL.
•
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 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 8 in " Electrical Characteristics" and footnote *4 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.
•
Because the SENSE pin has a high impedance, malfunctions may occur due to noise. Be careful of wiring adjoining
SENSE pin wiring in actual applications.
•
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.
•
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.
