Low ESR output capacitors (CL) can be used in the S-817 Serie s.
2. Output voltage (V OUT)
The accuracy of the output voltage is ±2.0% guaranteed under the specified con ditions for input voltage,
which differs depending upon the produ ct items, output current, and temperature.
Caution If the above conditions change, the ou tput voltage value may vary and go out of the
accuracy range of the o utput voltage. See the electrical char acte ristics and
characteristics data for d etails.

Operation
1. Basic Operation
Figure 14 shows the block diagram of the S-817 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 output transistor with the gate voltage necessary
to ensure a certain output voltage free of any fluctuations of input voltage and temperature.

2. Output Transistor
The S-817 series uses a P-channel MOS FET as the output transist or.
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 throu gh 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 ca se 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 ca pacitor.
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 capacit or is u sed 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”.

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-e m itter voltage (V BE) necessary to turn on the PNP transistor is obtain ed
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 t o power dissi pation under normal operation conditions.
• Resistor (R 1):
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 o n or due to power
or load fluctuation, but oscillation might occur. Always connect resistor R2 in series to outp ut
capacitor CL.
• Resistor (R 2): Set R2 to 2 Ω × VOUT(S) or more.
• DO NOT attach a capacitor between th e S-817 Series power sour ce (VIN) and GND pins or
between base and emitter of the PNP transistor to avoid oscillation.
• To improve transient response ch aracteristics 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) i s cal culated 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 Serie s b asically has.
To gain the driving ability which exceeds the S-817 Series, there’s a way to com bine a constant current
circuit and a current boosting circuit, as see n 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 th e 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 exam ple of input voltage between VIN and VO vs. IO current (Typ. Ta

The output voltage can be boosted by u sing 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 curre nt con su mption
(ISS).
Capacitor C1 is effective in minimizing ou tput 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 co nditions 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 resistan ce (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 connect ed.
• 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 o wned by a third party.
