Rev.3.1_02
The S-818 Series is a positive voltage regulator developed by CMOS technology and featured by low dropout
voltage, high output voltage accuracy and low current consumption.
Built-in low on-resistance transistor provides low dropout voltage and large output current. A ceramic
capacitor of 2 F or more can be used as an output capacitor. An ON/OFF circuit ensures long battery life.
The SOT-23-5 miniaturized package and the SOT-89-5 package are recommended for configuring portable
devices and large output current applications, respectively.

Caution The above connection diagram and constant will not guarantee successful operation.
Perform through evaluation using the actual application to set the constant.
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 2.0 % under the specified conditions of input voltage,
output current, and temperature, which differ product by product.
Caution When the above conditions are changed, the output voltage may vary and go out of the
accuracy range of the output voltage. Refer to the “ Electrical Characteristics” and
“ Characteristics (Typical Data)” for details.
3. Line regulation 1 (VOUT1) and Line regulation 2 (VOUT2
)
Line regulation indicates the input voltage dependence of the output voltage. The value shows how
much the output voltage changes due to the change of the input voltage when the output current is kept
constant.

4. Load regulation (VOUT3
)
Load regulation indicates the output current dependence of output voltage. The value shows how much
the output voltage changes due to the change of the output current when the input voltage is kept
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 the actual output
voltage VOUT(E)

Operation
1. Basic operation
Figure 12 shows the block diagram of the S-818 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-818 Series, a low on-resistance P-channel MOS FET is used as the output transistor.
Be sure that VOUT does not exceed VIN0.3 V to prevent the voltage regulator from being damaged due
to reverse current flowing from VOUT pin through a parasitic diode to the VIN pin, when the potential
of VOUT became higher than VIN.
12
LOW DROPOUT CMOS VOLTAGE REGULATOR
S-818 Series
Rev.3.1_02
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 becomes the VSS level due to the internally divided
resistance of several M between the VOUT pin and the VSS pin.
The structure of the ON/OFF pin is shown in Figure 13. Since the ON/OFF pin is neither pulled down
nor pulled up internally, do not use it in the floating status. In addition, note that the current consumption
increases if a voltage of 0.3 V to VIN – 0.3 V is applied to the ON/OFF pin. When not using the ON/OFF
pin, connect it to the VIN pin in the product A type, and connect it to the VSS pin in B type.

Selection of Output Capacitor (CL)
The S-818 Series needs an output capacitor between the VOUT pin and the VSS pin for phase
compensation. A small ceramic or an OS electrolyte capacitor of 2 F or more can be used. When a
tantalum or an aluminum electrolyte capacitor is used, the capacitance must be 2 F or more and the
ESR must be 10 or less.
Attention should be paid not to cause an oscillation due to increase of ESR at low temperatures when
an aluminum electrolyte capacitor is used.
Evaluate the performance including temperature characteristics before prototyping the circuit.
Overshoot and undershoot characteristics differ depending upon the type of the output capacitor. Refer
to the CL dependence data in “ Transient Response Characteristics (S-818A30A, Typical data,
Ta=25°C)”.

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
(10 mA or less).
Generally a series regulator may cause oscillation, depending on the selection of external parts. The
following conditions are recommended for the S-818 Series. However, be sure to perform sufficient
evaluation under the actual usage conditions for selection, including evaluation of temperature
characteristics.
Input capacitor (CIN):
Output capacitor (CL):
0.47F or more
2 F or more
Equivalent series resistance (ESR): 10 or less
Input series resistance (RIN): 10 or less
The voltage regulator may oscillate when the impedance of the power supply is high and the input
capacitor 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 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
5 in the “ Electrical Characteristics” and footnote *5 of the table.

any specific mass-production design.
ABLIC Inc. is not responsible for damages caused by the reasons other than the products described herein
(hereinafter "the products") or infringement of third-party intellectual property right and any other right due to the use
of the information described herein.
3. ABLIC Inc. is not responsible for damages caused by the incorrect information described herein.
4. Be careful to use the products within their specified ranges. Pay special attention to the absolute maximum ratings,
operation voltage range and electrical characteristics, etc.
ABLIC Inc. is not responsible for damages caused by failures and / or accidents, etc. that occur due to the use of the
products outside their specified ranges.
5. When using the products, confirm their applications, and the laws and regulations of the region or country where they
are used and verify suitability, safety and other factors for the intended use.
6. When exporting the products, comply with the Foreign Exchange and Foreign Trade Act and all other export-related
laws, and follow the required procedures.
7. The products must not be used or provided (exported) for the purposes of the development of weapons of mass
destruction or military use. ABLIC Inc. is not responsible for any provision (export) to those whose purpose is to
develop, manufacture, use or store nuclear, biological or chemical weapons, missiles, or other military use.
8. The products are not designed to be used as part of any device or equipment that may affect the human body, human
life, or assets (such as medical equipment, disaster prevention systems, security systems, combustion control
systems, infrastructure control systems, vehicle equipment, traffic systems, in-vehicle equipment, aviation equipment,
aerospace equipment, and nuclear-related equipment), excluding when specified for in-vehicle use or other uses. Do
not apply the products to the above listed devices and equipments without prior written permission by ABLIC Inc.
Especially, the products cannot be used for life support devices, devices implanted in the human body and devices
that directly affect human life, etc.
Prior consultation with our sales office is required when considering the above uses.
ABLIC Inc. is not responsible for damages caused by unauthorized or unspecified use of our products.
