ESR is the abbreviation for Equivalent Series Resistance.

Low ESR output capacitors (CL) can be used in the S-817 Series.

2. Output voltage (VOUT)

The accuracy of the output voltage is ±2.0% guaranteed 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. See the electrical characteristics and

characteristics data for details.

3. Line regulations 1 and 2 (ΔVOUT1, ΔVOUT2)

voltage changes due to a change in the input voltage with the output current remained unchanged.

4. Load regulation (ΔVOUT3)

Indicates the output current dependencies of output voltage. That is, the values show how much the

output voltage changes due to a change in the output current with the input voltage remained unchanged.

5. Dropout voltage (Vdrop)

Indicates a difference between input voltage (VIN1) and output voltage when output voltage falls by 98% of

 Operation

1. Basic Operation

Figure 14 shows the block diagram of the S-817 Series.

The error amplifier compares the reference voltage (Vref) with Vfb, which is the output voltage resistance-

divided by feedback resistors Rs and Rf. It supplies the output transistor with the gate voltage necessary

to ensure a certain output voltage free of any fluctuations of input voltage and temperature.

Figure 14

2. Output Transistor

The S-817 series uses a P-channel MOS FET 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 VOUT pin through a parastic diode to VIN pin.

3. Short Circuit Protection

The S-817A series incorporates a short circuit protection to protect the output transistor against short

circuit between VOUT pin and VSS pin. Installation of the short-circuit protection which protects the

output transistor against short-circuit between VOUT and VSS can be selected in the S-817A series. The

short-circuit protection controls output current as shown in the “Typical Characteristics 1.”. Output

Voltage versus Output Current, and suppresses output current at about 40 mA even if VOUT and VSS

pins are short-circuited.

The short-circuit protection can not be a thermal protection at the same time. Attention should be paid to

the Input voltage and the load current under the actual condition so as not to exceed the power

dissipation of the package including the case for short-circuit.

When the output current is large and the difference between input and output voltage is large even if not

shorted, the short-circuit protection may work and the output current is suppressed to the specified value.

For details, refer to “ Characteristics (Typical Data) 3. Maximum Output Current vs. Input

Voltage”.

In addition, S-817B series is removing a short-circuit protection, and is the product which enabled it to

pass large current.

 Selection of Output Capacitor (CL)

To stabilize operation against variation in output load, a capacitor (CL) must be mounted between VOUT

and VSS in the S-817 series because the phase is compensated with the help of the internal phase

compensation circuit and the ESR of the output capacitor.

When selecting a ceramic or an OS capacitor, capacitance should be 0.1 μF or more, and when selecting a

tantalum or an aluminum electrolytic capacitor, capacitance should be 0.1 μF or more and ESR 30 Ω or

less.

When an aluminum electrolytic capacitor is used attention should be especially paid to since the ESR of the

aluminum electrolytic capacitor increases at low temperature and possibility of oscillation becomes large.

Sufficient evaluation including temperature characteristics is indispensable. Overshoot and undershoot

characteristics differ depending upon the type of the output capacitor. Refer to CL dependencies in “

Reference Data 1. Transient Response Characteristics”.

Figure 15

As shown in Figure 15, the output current can be boosted by externally attaching a PNP transistor. The

base current of the PNP transistor is controlled so that output voltage (VOUT) goes the voltage specified

in the S-817 Series when base-emitter voltage (VBE) necessary to turn on the PNP transistor is obtained

between input voltage (VIN) and S-817 Series power source pin (VIN).

The following are tips and hints for selecting and ensuring optimum use of external parts

• PNP transistor (Tr1):

1. Set hFE to approx. 100 to 400.

2. Confirm that no problem occurs due to power dissipation under normal operation conditions.

• Resistor (R1):

Generally set R1 to 1 kΩ ÷ VOUT (S) (the voltage specified in the S-817 Series) or more.

• Output capacitor (CL):

Output capacitor (CL) is effective in minimizing output fluctuation at powering on or due to power

or load fluctuation, but oscillation might occur. Always connect resistor R2 in series to output

capacitor CL.

• Resistor (R2): Set R2 to 2 Ω × VOUT(S) or more.

• DO NOT attach a capacitor between the S-817 Series power source (VIN) and GND pins or

between base and emitter of the PNP transistor to avoid oscillation.

• To improve transient response characteristics of the output current boosting circuit shown in

Figure 15, check that no problem occurs due to output fluctuation at powering on or due to

power or load fluctuation under normal operating conditions.

• Pay attention to the short current limit circuit incorporated into the S-817 Series because it does

not function as a shortcircuiting protection circuit for this boosting circuit.

The S-817 Series can be configured as a constant current circuit. Refer to Figure 16 and 17.

Constant amperage (IO) is calculated using the following equation (VOUT(E): Effective output voltage):

IO = (VOUT(E) ÷ RL) +ISS.

Note that by using a circuit in Figure16, it is impossible to set the better driving ability to the constant

amperage (IO) than the S-817 Series basically has.

To gain the driving ability which exceeds the S-817 Series, there’s a way to combine a constant current

circuit and a current boosting circuit, as seen in Figure 17.

The maximum input voltage for a constant current circuit is 10 V + the voltage for device (VO).

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

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

The following is a characteristics example of input voltage between VIN and VO vs. IO current (Typ. Ta

= 25°C) in constant current boosting circuit in Figure 17.

The output voltage can be boosted by using the configuration shown in Figure 18. The output Voltage

(VO) can be calculated using the following equation (VOUT(E):Effective output voltage):

V

O = VOUT(E) × (R1 + R2) ÷ R1 + R2 × ISS

Set the values of resistors R1 and R2 so that the S-817 Series is not affected by current consumption

(ISS).

Capacitor C1 is effective in minimizing output fluctuation at powering on or due to power or load

fluctuation. Determine the optimum value on your actual device. But it is not also recommended to

attach a capacitor between the S-817 Series power source VIN and VSS pin or between output VOUT

and VSS pin because output fluctuation or oscillation at powering on might occur. As shown in Figure

18, a capacitor must be mounted between VIN and GND, and between VOUT and GND.

 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 the output voltage may increase when a series regulator is used at low load current (1.0 μA or

less).

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

following conditions are recommended for this IC. However, be sure to perform sufficient evaluation

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

Output capacitor (CL) : 0.1 μF or more

Equivalent Series Resistance (ESR) : 30 Ω or less

Input series resistance (RIN) : 10 Ω 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.

• The application conditions for the input voltage, output voltage, and 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.

• 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.
