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. Low ESR
ESR is the abbreviation for Equivalent Series Resistance. The low ESR output capacitor (CL) can be
used in the S-814 Series.
3. Output voltage (VOUT)
The accuracy of the output voltage is ensured at 2.0% under the specified conditions*1 of input voltage,
output current, and temperature, which differ depending upon the product items.
*1. The condition differs depending upon each product.
Caution If you change the above conditions, the output voltage value may vary out of the
accuracy range of the output voltage. Refer to “ Electrical Characteristics” and
“ Characteristics (Typical Data)” for details.
4. Line regulation 1 (VOUT1) and Line regulation 2 (VOUT2)
Indicates the input voltage dependencies of output voltage. That is, the value shows how much the
output voltage changes due to a change in the input voltage with the output current remained unchanged.
5. Load regulation (VOUT3)
Indicates the output current dependencies of output voltage. That is, the value shows how much the
output voltage changes due to a change in the output current with the input voltage remained unchanged.

Operation
1. Basic operation
Figure 12 shows the block diagram of the S-814 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-814 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 VIN pin, when the potential of VOUT
became higher than VIN.

Rev.3.1_02 S-814 Series

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 VIN pin and VOUT pin is turned off, reducing current
consumption significantly. The VOUT pin enters the Vss level due to internally divided resistance of
several M between VOUT pin and VSS pin.
Furthermore, the structure of the ON/OFF pin is as 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, please note that
current consumption increases if a voltage of 0.3 V to VIN0.3 V is applied to the ON/OFF pin. When not
using the ON/OFF pin, connect it to the VIN pin in case of the product A type, connect it to the VSS pin in
B type.

B “L”: ON Operate Set value ISS1
4. Short-circuit protection circuit
The S-814 Series incorporates a short-circuit protection circuit to protect the output transistor against
short-circuiting between VOUT pin and VSS pin.
The short-circuit protection circuit controls output current as shown in “1. Output voltage (VOUT) vs.
Output current (IOUT) (When load current increases)” in “ Characteristics (Typical Data)”, and
prevents output current of approx. 70 mA or more from flowing even if VOUT pin and VSS pin are shorted.
However, the short-circuit protection circuit does not protect thermal shutdown. Be sure that input voltage
and load current do not exceed the specified power dissipation level.
When output current is large and a difference between input and output voltages is large even if not
shorted, the short-circuit protection circuit may start functioning and the output current may be controlled
to the specified amperage. For details, refer to “3. Maximum output current (IOUTmax) vs. Input voltage
(VIN)” in“ Characteristics (Typical Data)”.

Selection of Output Capacitor (CL)
Mount an output capacitor between VOUT pin and VSS pin for phase compensation. The S-814 Series
enables customers to use a ceramic capacitor as well as a tantalum or an aluminum electrolytic capacitor.
A ceramic capacitor or an OS capacitor:
Use a capacitor of 0.47 F or more.
A tantalum or an aluminum electrolytic capacitor:
Use a capacitor of 0.47 F or more and ESR of 10 or less.
Pay special attention not to cause an oscillation due to an increase in ESR at low temperatures, when
you use the aluminum electrolytic capacitor. Evaluate the capacitor taking into consideration its
performance including temperature characteristics.
Overshoot and undershoot characteristics differ depending upon the type of the output capacitor you
select. Refer to CL dependencies of “1. Transient Response Characteristics (S-814A30A, Typical
data, Ta25C)” in “ Reference Data”.
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 A or less).
Generally a series regulator may cause oscillation, depending on the selection of external parts. The
following conditions are recommended for the S-814 Series. However, be sure to perform sufficient
evaluation under the actual usage conditions for selection, including evaluation of temperature
characteristics.
Output capacitor (CL): 0.47 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
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 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.
In determining the output current, attention should be paid to the output current value specified in Table 5
in “ Electrical Characteristics” and footnote *3 of the table.
Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in
electrostatic protection circuit.
