SUPER-SMALL PACKAGE CMOS VOLTAGE REGULATOR
S-817 Series
Seiko Instruments Inc.
1
The S-817 Series is a 3-terminal positive voltage
regulator, developed using CMOS technology. Small
ceramic capacitors can be used as the output
capacitor, and the S-817 series provides stable
operation with low loads down to 1 A.
Compared with the conventional voltage regulator, it is
of low current consumption, and with a lineup of the
super small package (SNT-4A:1.2 x 1.6mm). It is
optimal as a power supply of small portable device.
Features
Ultra-low current consumption: Operating current: Typ. 1.2 A, Max. 2.5 A
Output voltage:
1.1 to 6.0 V, selectable in 0.1 V steps.
Output voltage accuracy:
2.0%
Output current:
50 mA capable (3.0 V output product, V
IN
=5 V)
*1
75 mA capable (5.0 V output product, V
IN
=7 V)
*1
Dropout voltage:
Typ. 160 mV (V
OUT
= 5.0 V, I
OUT
= 10 mA)
Low ESR capacitor (e.g. A ceramic capacitor of 0.1 F or more) can be used as an output capacitor.
Short circuit protection for:
Series A
Excellent Line Regulation:
Stable operation at light load of 1
A
*1. Attention should be paid to the power dissipation of the package when the load is large.
Applications
Power source for battery-powered devices
Power source for personal communication devices
Power source for home electric/electronic appliances

Operation
1. Basic Operation
Figure 13 shows the block diagram of the S-817 Series.
The error amplifier compares the reference voltage (V
ref
) with V
fb
, which is the output voltage resistance-
divided by feedback resistors R
s
and R
f
. 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 transistor.
Be sure that V
OUT
does not exceed V
IN
+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.
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 (C
L
)
To stabilize operation against variation in output load, a capacitor (C
L
) 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
F or more, and when selecting a
tantalum or an aluminum electrolytic capacitor, capacitance should be 0.1
F or more and ESR 30 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 C
L
dependencies in "

As shown in Figure 14, 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 (V
OUT
) goes the voltage specified
in the S-817 Series when base-emitter voltage (V
BE
) necessary to turn on the PNP transistor is obtained
between input voltage (V
IN
) 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 h
FE
to approx. 100 to 400.
2. Confirm that no problem occurs due to power dissipation under normal operation conditions.
Resistor (R

):
Generally set R
1
to 1 k
V
OUT (S)
(the voltage specified in the S-817 Series) or more.
Output capacitor (C
L
):
Output capacitor (C
L
) 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 C
L
.
Resistor (R
2
): Set R
2
to 2
V
OUT(S)
or more.
DO NOT attach a capacitor between the S-817 Series power source (V
IN
) 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 14, 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 15 and 16.

.
Please note that it is impossible to set constant amperage I

in case of circuit (1) of Figure 15 to the
value exceeding the drive ability of the S-817.
However, circuit (2) of Figure 16 is an example to set constant amperage to the value exceeding the
drive ability of the S-817. Circuit (2) incorporates a current boosting circuit. The maximum input voltage
of the constant current circuit is the value obtained by adding 10 V to voltage of the device (V
O
). It is not
recommended to attach a capacitor between the S-817 power source VIN and VSS pin or between
output VOUT and VSS pin because rush current flows at powering on. An example of input voltage

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
17, 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 (C
L
) and a capacitor for stabilizing
the input between VIN and VSS pins (C
IN
), 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 A 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 (C
L
) :
0.1
F or more
Equivalent Series Resistance (ESR) : 30
or less
Input series resistance (R
IN
) :
10
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.
