• Low current consumption: Current at operation: Typ. 1.0 μA, Max. 1.8 μA (product with 3.0 V)
• Output voltage: 2.0 to 6.0 V, selectable in 0.1 V step.
• Output voltage accuracy: ±2.0%
• Output current: 50 mA capable (3.0 V output product, VIN=5 V) *1
75 mA capable (5.0 V output product, VIN=7 V) *1
• Dropout voltage: Typ. 120 mV (VOUT = 5.0 V, IOUT = 10 mA)
• Built-in Power-off circuit: Selectable if power-off function is available or not.
Active high or low in the regulator is selectable.
• Short-circuit protection: Selectable with/without short-circuit protection.

Technical Terms
1. Output capacitors (CL)
Generally in voltage regulator, output capacitor is used to stabilize regulation and to improve the
characteristics of transient response. The S-812C Series operates stably without output capacitor CL.
Thus the output capacitor CL is used only for improvement of the transient response. In the applications
that users will use the S-812C Series, and they are not cautious about the transient response, it is
possible to omit an output capacitor. If using an output capacitor for this IC, users are able to use devices
such as ceramic capacitor which has sm all E S R (E quivalent Series Resi stance).
2. Output voltage (VOUT)
The accuracy of the output voltage ± 2.0% is assured under the specified conditions for input voltage,
which differs depending upon the produ c t items, output current, and temperature.
Caution If the above conditions chan ge, the output voltage value may vary and go out of the
accuracy range of the output voltage. See the electrical characte ristics and
characteristics data for d etails.
3. Line regulations 1 and 2 (ΔVOUT1, ΔVOUT2)
Indicate the dependency of the output voltage against the input voltage. That is, the value shows h ow
much the output voltage changes due to a change in the input voltage after fixing output current constant.
4. Load regulation (ΔVOUT3)
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 cu rrent after fixing output current
constant.
5. Dropout voltage (Vdrop)
Indicates the difference betwee n the output voltage and the input voltage VIN1, which is the input voltage
(VIN) when; decreasing input voltage VIN gradually until the output voltage has dropped to the value of
98% of output voltage VOUT(E), which is at VIN = VOUT(S) + 1.0 V.
Vdrop = VIN1 − (VOUT(E) × 0.98)

Operation
1. Basic Operation
Figure 16 shows the block diagram of the S-812C Series.
The error amplifier compa r es the reference voltage (Vref) with Vfb, which is the output voltage resi stance-
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. Parasitic diode Figure 16
2. Output Transistor
In the S-812C Series, a low on-resistance P-channel MOS FET is used as the o utput tran sistor.
Be sure that VOUT does not exceed VIN + 0.3 V to prevent the voltage regulator from being damaged d ue
to inverse current which flows, be cause of a parasitic diode between the VIN and VOUT pin.

S-812C Series Rev.6.1_00

3. Power-off function (ON/OFF pin)
This function starts and sto ps the regulator.
When the ON/OFF pin is set to power-off level, the entire internal circuit stops operating, and the built-in
P-channel MOS FET output transistor between the VIN and VOUT pin is turned off, in order to reduce
the current consumption si gnificantly. The VOUT pin is set to the VSS level by the internal dividing
resistor of several MΩ between the VOUT and VSS pin.
The ON/OFF pin is configured as shown in Figure 17 Since the ON/OFF pin is neither pulled down nor
pulled up internally, do not use it in the floating state. Note that if applying the voltage of VIN + 0.3 V or
more, the current flows to VIN via a parasitic diode in the IC.
When not using the power-off pin in the product with the po wer-off function, connect the ON/OFF pin to
the VIN pin (in positive logic), or to the VSS pin (in ne gative logic).
The output voltage may increase by stopping regulation whe n a lower current (less than 100 μA) is
applied.
If the output voltage increased during power-off, pull the VOUT pin down to the VSS pin and set the
ON/OFF pin to the power-down level.

4. Short-circuit protection circuit
In the S-812C Series, users are able to select whether to set the short circuit protection, which prote cts
the output capacitor from short-circuiting the VOUT and VSS pin.
The short circuit protection circuit controls the output current against voltage VOUT, as seen in “
Characteristics (Typical Data) 1”, and limits the output current at approx. 40 mA even if the VOUT and
VSS pins are short-circuited.
However, this short circuit protection circuit doe s not work as for thermal protection. Pay attention to the
conditions of input voltage and load current so that, under the usag e con dition including short circuit, the
loss of the IC will not exceed power dissipation of the package.
Even if pins are not short-circuited, this protectio n circuit works to li mit the curren t to the specified value,
in order to protect the output capacitor, whe n the output curre nt and the potential difference between
input and output voltages increase.
In the product without the short circuit protection circuit, the S-812C Series allows the relatively larger
current because this protection circuit is detached.

Selection of External Components
1. Output Capacitor (CL)
The S-812C Series has an internal phase compensation circuit whi ch sta bilizes the operation regardl ess
of the change of output load. Therefore it is possible for users to ha ve a stable operation without an
output capacitor (CL). However, the values of output overshoot and undershoot, which are the
characteristics of transient response, vary depending on the output capacitor. In sele cting the value of
output capacitor, refer to the data on CL dependency in “ Reference data 1. Transient response
characteristics”.
Set ESR 10 Ω or less when using a tantalum ca pacitor or an aluminum electrolytic capacitor. Pay
attention at low temperature, that aluminum electrolytic capacitor especially may oscillate because ESR
increases. Evaluate sufficiently including the temperature cha racteri stics in use.
Application Circuit
1. Output Current Boost Circuit
As shown in Figure 18, the output current can be boosted by externally attaching a PNP transistor.
Between the input voltage VIN and the VIN pin (for po wer supply) in the S-812C Series, if setting the
base-emitter voltage VBE which fully switches the PNP transistor on, S-812C Series controls the base
current in a PNP transistor so that the output voltage VOUT reaches t he level of voltage which is set by
the S-812C Series.
Since the output current boosting circuit in Figure 18 doe s not have the good characteri stics of transient
response, under the usage conditio n, confirm if output fluctuation due to power-on, and fluctuations of
power supply and load affect on the operation or not before use.
Note that the short-circuit protection circuit in the S-812C Series does not work as short -circuit protection
for this boost circuit.

2. Constant Current Circuit
This circuit can be used as a constant curre nt circuit if makin g the composition seen in Figure 19 and
20. Constant current IO is calculated from the followin g equatio n:
IO = (VOUT(E) ÷ RL) + ISS
(VOUT(E) = effective output voltage)
Note that by using a circuit in Figure 19, it is impossible to set the better driving ability to the constant
amperage (IO) than the S-812C Series basically has.
To gain the driving ability which exceeds the S-812C Serie s, there’ s a way to combine a constant
current circuit and a curren t boosting circuit, as seen in Figure 20.
The maximum input voltage for a constant current circuit is 16 V + the voltage for device (VO).
It is not recommended to add a capacitor between th e VIN (power supply) and VSS pin or the VOUT
(output) and VSS pin because the rush current flows at power-on.

3. Output Voltage Adjustment Circuit
(Only for S-812CxxA Series (No short-circuit protection, power-off function))
By using the composition seen in Figure 21, users are able to increase the output voltage. The value of
output voltage VOUT1 is calculated from the following equation:
VOUT1 = VOUT(E) × (R1 + R2) ÷ R1 + R2 × ISS
(VOUT(E) = effective output voltage)
Set the value of resistors R1 and R2 so that the S-812C Series is not affected by current cons umption
ISS.
Capacitor C1 reduces output fluctuation due to power-on, power flu ctuation a nd load fluctuation. Set the
value according to the actual evaluation.
It is not recommended to add a capacitor between th e VIN (power supply) and VSS pin or the VOUT
(output) and VSS pin because it causes output fluctuation and output oscillation due to power-on.

Precautions
• Wiring patterns for the VIN, VOUT and GND pins should be designed so that the impedance is low. When
mounting an output capacitor between the VOUT and VSS pins (CL) and a capacitor for stabilizing the
input between VIN and VSS pins (CIN), the distance from the capacitors to these pins should be as short
as possible.
• Note that output voltage may be increased at low load current of less than 1 μA.
• At low load current less than 100 μA output voltage may increase when the reg ulating operation is halted
by the ON/OFF pin.
• To prevent oscillation, it is recommended to use the external parts under the foll owing conditions.
Equivalent Series Resistance (ES R): 1 0 Ω or less (in case of using output capacitor)
Input series resistan ce (RIN): 10 Ω or less
• A voltage regulator may oscillate when power source impedance is high and in put cap acitor is low or not
connected.
• Pay attention to the operating conditions for input/output voltage and load current so that the power loss in
the IC does not exceed the power dissipation of the packag e.
• Do not apply an electrostatic disch arg e to this IC that exceeds the performance ratings of the built-in
electrostatic protection circuit.
• SII claims no responsibility for any and all disputes a rising out of or in connectio n with any infringe ment of
the products including this IC upo n patents owned by a third party.
