HA17431 Series
Shunt Regulator
Description
The HA17431 series is a family of voltage referenced shunt regulators. The main application of these
products is in voltage regulators that provide a variable output voltage. The HA17431 series products are
provided in a wide range of packages; TO-92 and TO-92MOD insertion mounting packages and MPAK-5,
UPAK, and FP-8D surface mounting packages are available. The on-chip high-precision reference voltage
source can provide ±1% accuracy in the V versions, which have a VKA max of 16 volts. The
HA17431VLP, which is provided in the MPAK-5 package, is designed for use in switching mode power
supplies. It provides a built-in photocoupler bypass resistor for the PS pin, and an error amplifier can be
easily constructed on the supply side.

Application Examples
As shown in the figure on the right, this IC operates as an inverting amplifier, with the REF pin as input
pin. The open-loop voltage gain is given by the reciprocal of “reference voltage deviation by cathode
voltage change” in the electrical specifications, and is approximately 50 to 60 dB. The REF pin has a high
input impedance, with an input current Iref of 3.8 µA Typ (V version: Iref = 2 µA Typ). The output
impedance of the output pin K (cathode) is defined as dynamic impedance Z KA , and ZKA is low (0.2 Ω) over
a wide cathode current range. A (anode) is used at the minimum potential, such as ground.

This is the simplest reference voltage circuit. The value
of the resistance R is set so that cathode current IK ≥ 1

The external capacitor CL (CL ≥ 3.3 µF) is used to
prevent oscillation in normal applications.
This is circuit 1 above with variable output provided.
Here, Vout ≅ 2.5 V ×
(R1 + R2)
R2
Since the reference input current Iref = 3.8 µA Typ (V
version: Iref = 2 µA Typ) flows through R 1, resistance
values are chosen to allow the resultant voltage drop to
be ignored.

The requirement in this circuit is that the cathode
current must be greater than Imin = 1 mA. The IL
setting therefore must be on the order of several mA or
more.

In this circuit, the load is connected on the collector side
of transistor Q in circuit 7 above. In this case, the load
floats from GND, but the HA17431 cathode current is
not superimposed on IL, so that IL can be kept small (1
mA or less is possible). The constant current value is
the same as for circuit 7 above:

Use of Shunt Regulator in Transformer Secondary Side Control
This example is applicable to both forward transformers and flyback transformers. A shunt regulator is
used on the secondary side as an error amplifier, and feedback to the primary side is provided via a
photocoupler.

Determination of External Constants for the Shunt Regulator
DC characteristic determination: In figure 2, R1 and R2 are protection resistor for the light emitting diode
in the photocoupler, and R2 is a bypass resistor to feed IK minimum, and these are determined as shown
below. The photocoupler specification should be obtained separately from the manufacturer. Using the
parameters in figure 2, the following formulas are obtained:
R1 =
V0 – VF – VK
V
, R2 = F
IF + IB
IB
VK is the HA17431 operating voltage, and is set at around 3 V, taking into account a margin for fluctuation.
R 2 is the current shunt resistance for the light emitting diode, in which a bias current I B of around 1/5 IF
flows.
Next, the output voltage can be determined by R3 and R4, and the following formula is obtained:
V0 =
R3 + R4
× Vref, Vref = 2.5 V Typ
R4
The absolute values of R3 and R4 are determined by the HA17431 reference input current Iref and the AC
characteristics described in the next section. The Iref value is around 3.8 µA Typ. (V version: 2 µA Typ)

AC characteristic determination: This refers to the determination of the gain frequency characteristic of
the shunt regulator as an error amplifier. Taking the configuration in figure 2, the error amplifier
characteristic is as shown in figure 3.

Practical Example
Consider the example of a photocoupler, with an internal light emitting diode VF = 1.05 V and I F = 2.5 mA,
power supply output voltage V2 = 5 V, and bias resistance R2 current of approximately 1/5 IF at 0.5 mA. If
the shunt regulator VK = 3 V, the following values are found.
R1 =
5V – 1.05V – 3V
= 316(Ω) (330Ω from E24 series)
2.5mA + 0.5mA
R2 =
1.05V
= 2.1(kΩ) (2.2kΩ from E24 series)
0.5mA
Next, assume that R3 = R4 = 10 kΩ. This gives a 5 V output. If R5 = 3.3 kΩ and C1 = 0.022 µF, the
following values are found.
G2 = 3.3 kΩ / 10 kΩ = 0.33 times (–10 dB)
f 1 = 1 / (2 × π × 0.022 µF × 316 × 10 kΩ) = 2.3 (Hz)
f 2 = 1 / (2 × π × 0.022 µF × 3.3 kΩ) = 2.2 (kHz)
