Seiko Instruments Inc. 1
The S-13A1 Series is a positive voltage regulator with a low dropout voltage, high-accuracy output voltage, and low current
consumption developed based on CMOS technology.
A 2.2 μF small ceramic capacitor can be used, and the very small dropout voltage and the large output current due to the
built-in transistor with low on-resistance are provided. The S-13A1 Series includes a load current protection circuit that
prevents the output current from exceeding the current capacitance of the output transistor and a thermal shutdown circuit
that prevents damage due to overheating. In addition to the types in which output voltage is set inside the IC, a type for
which output voltage can be set via an external resistor is added to a lineup. Also, the S-13A1 Series includes an inrush
current limit circuit to limit the excess inrush current generated at power-on or at the time when the ON / OFF pin is set to
ON. High heat radiation HSOP-6 and small SOT-89-5, HSNT-6A packages realize high-density mounting.
Features
• Output voltage (internally set): 1.0 V to 3.5 V, selectable in 0.05 V step
• Output voltage (externally set): 1.05 V to 5.0 V, settable via external resistor
(HSOP-6, SOT-89-5 only)
• Input voltage: 1.5 V to 5.5 V
• Output voltage accuracy: ±1.0% (internally set, 1.0 V to 1.45 V output product: ±15 mV)
• Dropout voltage: 70 mV typ. (3.0 V output product, IOUT = 300 mA)
• Current consumption: During operation: 60 μA typ., 90 μA max.
During power-off: 0.1 μA typ., 1.0 μA max.
• Output current: Possible to output 1000 mA (VIN ≥ VOUT(S) + 1.0 V)*1
• Input and output capacitors: A ceramic capacitor of 2.2 μF or more can be used.
• Ripple rejection: 70 dB typ. (f = 1.0 kHz)
• Built-in overcurrent protection circuit: Limits overcurrent of output transistor.
• Built-in thermal shutdown circuit: Prevents damage caused by heat.
• Built-in inrush current limit circuit: Limits excessive inrush current generated at power-on or at the time when
the ON / OFF pin is set to ON.
For types in which output voltage is internally set of HSOP-6, SOT-89-5,
inrush current limit time can be changed via external resistor (CSS).

Caution The above connection diagram and constant will not guarantee successful operation. Perform
thorough evaluation using the actual application to set the constant.

Condition of Application
Input capacitor (CIN): 2.2 μF or more
Output capacitor (CL): 2.2 μF or more
Caution 1. Set input capacitor (CIN) and output capacitor (CL) as CIN = CL.
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-13A1 Series requires an output capacitor between the VOUT and 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.
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 ≥ 2.2 μF
• CL ≥ 2.2 μF
• CIN = CL
Caution The S-13A1 Series may oscillate if setting the value as CIN ≥ 2.2 μF, CL ≥ 2.2 μF, CIN < CL.
Define the values by sufficient evaluation including the temperature characteristics under the usage
condition.
Selection of Capacitor for Inrush Current Limit (CSS)
(Types in Which Output Voltage is Internally Set of HSOP-6, SOT-89-5)
In the S-13A1 Series, the inrush current limit time (tRUSH) is adjustable by connecting a capacitor for inrush current limit
(CSS) between the SSC and VSS pins. The time that the output voltage rises to 99% is 0.7 ms typ. when CSS = 1.0 nF.
The S-13A1 Series operates stably even with no CSS connection (in the state the SSC pin is leaved open).
The recommended value for CSS is 0 nF*1 ≤ CSS ≤ 22 nF, however, define the values by sufficient evaluation including
the temperature characteristics under the usage condition.
*1. In case the S-13A1 Series is used without CSS connection (CSS = 0 nF), be sure to leave the SSC pin open and do
not connect it to the VIN and VSS pins.

Operation
1. Basic operation
Figure 30 shows the block diagram the S-13A1 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-13A1 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 inverse
current flowing from the VOUT pin through a parasitic diode to the VIN pin.

3. ON / OFF pin
This pin starts and stops the regulator.
When the ON / OFF pin is set to the OFF level, the entire internal circuit stops operating, and the built-in P-channel MOS
FET output transistor between the VIN and VOUT pins is turned off, reducing current consumption significantly. 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 31 and Figure 32.
3. 1 S-13A1 Series A / C type
The ON / OFF pin is internally pulled down to the VSS pin in the floating status, so the VOUT pin is set to the VSS
level.
3. 2 S-13A1 Series B / D type
The ON / OFF pin is not internally pulled down to the VSS pin, so do not use these types with the ON / OFF pin in
the floating status. When not using the ON / OFF pin, connect the pin to the VIN pin.

4. Discharge shunt function (S-13A1 Series A / B type)
The S-13A1 Series A / B 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-13A1 Series C / D type does not have a discharge shunt circuit, the VOUT pin is set to VSS level through
several hundred kΩ internal divided resistors between the VOUT pin and the VSS pin. The S-13A1 Series A / B type
allows the VOUT pin to reach the VSS level rapidly due to the discharge shunt circuit.

6. Overcurrent protection circuit
The S-13A1 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 and VSS pin.
The current (Ishort) when the output pin is short-circuited 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.
7. Thermal shutdown circuit
The S-13A1 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 120°C typ., the thermal shutdown circuit is released to restart regulating.
Due to self-heating of the S-13A1 Series, if the thermal shutdown circuit starts operating, it stops regulating so that the
output voltage drops. When regulation stops, the S-13A1 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-13A1
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 voltage in order to
reduce the internal current consumption, or decreasing the ambient temperature.

8. Inrush current limit circuit
The S-13A1 Series has a built-in inrush current limit circuit to suppress the inrush current and the overshoot of the
output voltage generated at power-on or at the time when the ON / OFF pin is set to ON. The inrush current is limited
to 500 mA typ. The inrush current limit circuit starts to operate from the following times.
• Immediately after power-on
• At the time when the ON / OFF pin is set to ON
Figure 34 shows the relation between the inrush current limit time (tRUSH) and the inrush current limit capacitor (CSS).

tRUSH is determined by the internal capacitor (about 20 pF) and the time constant of the built-in constant current
(about 0.04 μA). tRUSH value is 0.28 ms min., 0.40 ms typ., 0.52 ms max.
(2) CSS

tRUSH can be adjusted by the CSS which is connected externally between the SSC*1 and VSS pins. It is calculated by
the following formula depending on the built-in constant (about 1 μA) and the CSS time constant.
The inrush current limit coefficient is 0.49 min., 0.7 typ., 0.91 max. at Ta = +25°C.
tRUSH [ms] = the inrush current limit coefficient × CSS [nF]
(3) 0 nF < CSS < 1 nF
Since the internal capacitor, the built-in constant current and CSS have a variation each, tRUSH is the one of following
(a) and (b) in which the time is longer.
(a) The time determined by the internal capacitor (about 20 pF) and the time constant of the built-in constant
current (about 0.04 μA).
(b) The time determined by CSS connected externally between the SSC*1 and VSS pins and the built-in constant
current (about 1 μA).
When 0 nF < CSS< 1 nF, tRUSH is the range of the shaded area shown in Figure 34.

9. Externally setting output voltage (HSOP-6, SOT-89-5 only)
The S-13A1 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 VOUT and VADJ pins, and a resistor (Rb) between VADJ and VSS
pins.
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.

The following expression is in order to determine output voltage VOUT = 3.0 V.
If resistance Rb = 2 kΩ, substitute internal resistance in adjust pin RVADJ = 400 kΩ typ. into (3),
Resistance Ra = (3.0 / 1.0 − 1) × ((2 k × 400 k) / (2 k + 400 k)) ≅ 4.0 kΩ
Caution The above connection diagrams and constants will not guarantee successful operation. Perform
thorough evaluation using the actual application to set the constants.

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 and VSS pins (CL), a capacitor for stabilizing the input between the
VIN and VSS pins (CIN), and a capacitor for limiting the inrush current between the SSC and VSS pins (CSS), 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.
• Generally a series regulator may cause oscillation, depending on the selection of external parts. The following
conditions are recommended for the S-13A1 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): 2.2 μF or more
Output capacitor (CL): 2.2 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.
• 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 15 and
Table 16 in " Electrical Characteristics" and footnote *5 of the table.
• SII 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.
