S-812C Series Rev.7.0_01

 Explanation of Terms

1. Output capacitor (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 small ESR (Equivalent Series Resistance).

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 product items, output current, and temperature.

Caution If the above conditions change, the output voltage value may vary and go out of the

accuracy range of the output voltage. Refer to " Electrical Characteristics" and "

Characteristics (Typical Data)" for details.

3. Line regulations 1 and 2 (VOUT1, VOUT2)

Indicate 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.

4. Load regulation (VOUT3)

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 output current

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)).

Vdrop = VIN1  (VOUT(E)  0.98)

 Operation

1. Basic operation

Figure 17 shows the block diagram of the S-812C 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-812C 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 reverse current flowing from the VOUT pin through a parasitic diode to the VIN pin, when the potential

of VOUT became higher than VIN.

16 V INPUT, 75 mA VOLTAGE REGULATOR

Rev.7.0_01 S-812C 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 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 as shown in Figure 18. Since the ON/OFF pin is neither pulled down

nor pulled up internally, do not use it in the floating status. 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 ON/OFF pin in the product with the power-off function, connect the ON/OFF pin to

the VIN pin (in positive logic), or to the VSS pin (in negative logic).

The output voltage may increase by stopping regulation when a lower current (100 A or less) 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 protects

the output capacitor from short-circuiting between the VOUT pin and the VSS pin.

The short circuit protection circuit controls the output current against voltage VOUT, as seen in “

Characteristics (Typical Data)”, “1. Output Voltage vs Output Current (When load current

increases)”, and limits the output current at approx. 40 mA even if the VOUT pin and the VSS pins are

short-circuited.

However, this short circuit protection circuit does not work as for thermal protection. Pay attention to the

conditions of input voltage and load current so that, under the usage condition including short circuit, the

loss of the IC will not exceed power dissipation of the package.

Even if pins are not short-circuited, this protection circuit works to limit the current to the specified value,

in order to protect the output capacitor, when the output current 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.

16 V INPUT, 75 mA VOLTAGE REGULATOR

S-812C Series Rev.7.0_01

 Selection of External Components

1. Output capacitor (CL)

The S-812C Series has an internal phase compensation circuit which stabilizes the operation regardless

of the change of output load. Therefore it is possible for users to have 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 selecting the value of

output capacitor, refer to the data on CL dependency in “ Reference data”, “1. Transient response

characteristics (Typical data: Ta25 C)”.

Set ESR 10  or less when using a tantalum capacitor 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 characteristics in use.

 Application Circuit

1. Output current boost circuit

As shown in Figure 19, the output current can be boosted by externally attaching a PNP transistor.

Between the input voltage VIN and the VIN pin (for power 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 the level of voltage which is set by

the S-812C Series.

Since the output current boosting circuit in Figure 19 does not have the good characteristics of transient

response, under the usage condition, 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 current circuit if making the composition seen in Figure 20 and

21. Constant current IO is calculated from the following equation (VOUT(E) = actual output voltage):

IO = (VOUT(E)  RL) + ISS

Note that by using a circuit in Figure 20, 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 Series, there’s a way to combine a constant

current circuit and a current boosting circuit, as seen in Figure 21.

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 the VIN pin (power supply) and the VSS pin or the

VOUT pin (output) and the VSS pin because the rush current flows at power-on.

3. Output voltage adjustment circuit

(Only for S-812CxxA Series (Unavailable short-circuit protection and power-off function))

By using the composition seen in Figure 22, users are able to increase the output voltage. The value of

output voltage VOUT1 is calculated from the following equation (VOUT(E) = actual output voltage):

VOUT1 = VOUT(E)  (R1 + R2)  R1 + R2  ISS

Set the value of resistors R1 and R2 so that the S-812C Series is not affected by current consumption

ISS.

Capacitor C1 reduces output fluctuation due to power-on, power fluctuation and load fluctuation. Set the

value according to the actual evaluation.

It is not recommended to add a capacitor between the VIN pin (power supply) and the VSS pin or the

VOUT pin (output) and the VSS pin because it causes output fluctuation and output oscillation due to

power-on.

 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

(1 A or less).

 At low load current (100 A or less) output voltage may increase when the regulating operation is halted

by the ON/OFF pin.

 Generally a series regulator may cause oscillation, depending on the selection of external parts. The

following conditions are recommended for the S-812C Series. However, be sure to perform sufficient

evaluation under the actual usage conditions for selection, including evaluation of temperature

characteristics.

Equivalent Series Resistance (ESR): 10  or less (in case of using output capacitor)

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.

 Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in

electrostatic protection circuit.

 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.

 Precautions for WLP package

● The side of device silicon substrate is exposed to the marking side of device package. Since this portion has lower

strength against the mechanical stress than the standard plastic package, chip, crack, etc should be careful of the

handing of a package enough. Moreover, the exposed side of silicon has electrical potential of device substrate, and

needs to be kept out of contact with the external potential.

● In this package, the overcoat of the resin of translucence is carried out on the side of device area. Keep it mind that it

may affect the characteristic of a device when exposed a device in the bottom of a high light source.
