TLVH431, TLVH432 Low-Voltage Adjustable Precision Shunt Regulators
1 Features
3 Description
•
•
The TLVH431 and TLVH432 devices are low-voltage
3-terminal adjustable voltage references, with
specified thermal stability over applicable industrial
and commercial temperature ranges. Output voltage
can be set to any value between VREF (1.24 V) and
18 V with two external resistors (see Figure 19).
These devices operate from a lower voltage (1.24 V)
than the widely used TL431 and TL1431 shuntregulator references.

•
•
•
•
•
•
Low-voltage operation: down to 1.24 V
Reference voltage tolerances at 25°C
– 0.5% for B grade
– 1% for A grade
– 1.5% for standard grade
Adjustable output voltage, VO = VREF to 18 V
Wide operating cathode current range:
100 μA to 70 mA
0.25-Ω typical output impedance
–40°C to +125°C specifications
TLVH432 provides alternative pinouts for
SOT-23-3 and SOT-89 packages
Ultra-small SC-70 package offers 40%
smaller footprint than SOT-23-3
When used with an optocoupler, the TLVH431 and
TLVH432 devices are ideal voltage references in
isolated feedback circuits for 3-V to 3.3-V switchingmode power supplies. They have a typical output
impedance of 0.25 Ω. Active output circuitry provides
a very sharp turn-on characteristic, making the
TLVH431
and
TLVH432
devices
excellent
replacements for low-voltage Zener diodes in many
applications, including on-board regulation and
adjustable power supplies.
2 Applications
•
•
•
•
•
Adjustable voltage reference for data Converters
Secondary side regulation in flyback SMPSs
Zener replacement with low leakage current
Voltage monitoring for power rails
Comparator with integrated reference
The TLVH432 device is identical to the TLVH431
device, but is offered with different pinouts for the
3-pin SOT-23 and SOT-89 packages.

8 Detailed Description
8.1 Overview
TLVH431 is a low power counterpart to TL431, having lower reference voltage (1.24 V versus 2.5 V) for lower
voltage adjustability and lower minimum cathode current (Ik(min)= 100 µA versus 1 mA). Like TL431, TLVH431 is
used in conjunction with its key components to behave as a single voltage reference, error amplifier, voltage
clamp or comparator with integrated reference.
TLVH431 is also a higher voltage counterpart to TLV431, with cathode voltage adjustability from 1.24 V to 18 V,
making this part optimum for a wide range of end equipments in industrial, auto, telecom and computing. In order
for this device to behave as a shunt regulator or error amplifier, >100 µA (Imin(max)) must be supplied in to the
cathode pin. Under this condition, feedback can be applied from the Cathode and Ref pins to create a replica of
the internal reference voltage.
Various reference voltage options can be purchased with initial tolerances (at 25°C) of 0.5%, 1%, and 1.5%.
These reference options are denoted by B (0.5%), A (1.0%) and blank (1.5%) after the TLVH431.
The TLVH431xC devices are characterized for operation from 0°C to 70°C, the TLVH431xI devices are
characterized for operation from –40°C to +85°C, and the TLVH431xQ devices are characterized for operation
from –40°C to +125°C.

8.3 Feature Description
TLVH431 consists of an internal reference and amplifier that outputs a sink current base on the difference
between the reference pin and the virtual internal pin. The sink current is produced by an internal Darlington pair.
When operated with enough voltage headroom (≥ 1.24 V) and cathode current (Ika), TLVH431 forces the
reference pin to 1.24 V. However, the reference pin can not be left floating, as it needs Iref ≥ 0.5 µA (see
Specifications). This is because the reference pin is driven into an NPN, which needs base current in order
operate properly.
When feedback is applied from the Cathode and Reference pins, TLVH431 behaves as a Zener diode, regulating
to a constant voltage dependent on current being supplied into the cathode. This is due to the internal amplifier
and reference entering the proper operating regions. The same amount of current needed in the above feedback
situation must be applied to this device in open loop, servo or error amplifying implementations in order for it to
be in the proper linear region giving TLVH431 enough gain.
Unlike many linear regulators, TLVH431 is internally compensated to be stable without an output capacitor
between the cathode and anode. However, if it is desired to use an output capacitor Figure 15, Figure 16, and
Figure 17 can be used as a guide to assist in choosing the correct capacitor to maintain stability.

8.4 Device Functional Modes
8.4.1 Open Loop (Comparator)
When the cathode/output voltage or current of TLVH431 is not being fed back to the reference/input pin in any
form, this device is operating in open loop. With proper cathode current (Ika) applied to this device, TLVH431 has
the characteristics shown in Figure 4. With such high gain in this configuration, the TLVH431 device is typically
used as a comparator. With the reference integrated makes TLVH431 the preferred choice when users are trying
to monitor a certain level of a single signal.
8.4.2 Closed Loop
When the cathode/output voltage or current of TLVH431 is being fed back to the reference/input pin in any form,
this device is operating in closed loop. The majority of applications involving TLVH431 use it in this manner to
regulate a fixed voltage or current. The feedback enables this device to behave as an error amplifier, computing
a portion of the output voltage and adjusting it to maintain the desired regulation. This is done by relating the
output voltage back to the reference pin in a manner to make it equal to the internal reference voltage, which can
be accomplished through resistive or direct feedback.

9 Applications and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
9.1 Application Information
Figure 23 shows the TLVH431, TLVH431A, or TLVH431B used in a 3.3-V isolated flyback supply. Output voltage
VO can be as low as reference voltage VREF (1.24 V ± 1%). The output of the regulator, plus the forward voltage
drop of the optocoupler LED (1.24 + 1.4 = 2.64 V), determine the minimum voltage that can be regulated in an
isolated supply configuration. Regulated voltage as low as 2.7 Vdc is possible in the topology shown in
Figure 23.
The TLVH431 family of devices are prevalent in these applications, being designers go to choice for secondary
side regulation. Due to this prevalence, this section explains operation and design in both states of TLVH431 that
this application will see, open loop (Comparator + VREF) and closed loop (Shunt Regulator).
Further information about system stability and using a TLVH431 device for compensation see Compensation
Design With TL431 for UCC28600, SLUA671.

9.2.1.2 Detailed Design Procedure
When using TLVH431 as a comparator with reference, determine the following:
• Input voltage range
• Reference voltage accuracy
• Output logic input high and low level thresholds
• Current source resistance
9.2.1.2.1 Basic Operation
In the configuration shown in Figure 24, TLVH431 behaves as a comparator, comparing the Vref pin voltage to
the internal virtual reference voltage. When provided a proper cathode current (Ik), TLVH431 will have enough
open loop gain to provide a quick response. With the TLVH431's max Operating Current (Imin) being 100 uA and
up to 150 uA over temperature, operation below that could result in low gain, leading to a slow response.

9.2.1.2.2 Overdrive
Slow or inaccurate responses can also occur when the reference pin is not provided enough overdrive voltage.
This is the amount of voltage that is higher than the internal virtual reference. The internal virtual reference
voltage will be within the range of 1.24 V ±(0.5%, 1.0% or 1.5%) depending on which version is being used.
The more overdrive voltage provided, the faster the TLVH431 will respond. See figures Figure 25 and Figure 26,
for the output responses to various input voltages.
For applications where TLVH431 is being used as a comparator, it is best to set the trip point to greater than the
positive expected error (that is, +1.0% for the A version). For fast response, setting the trip point to > 10% of the
internal Vref should suffice.
For minimal voltage drop or difference from Vin to the ref pin, it is recommended to use an input resistor 5° to guarantee stability of the TLVH431.

10 Power Supply Recommendations
When using TLVH431 as a Linear Regulator to supply a load, designers will typically use a bypass capacitor on
the output/cathode pin. When doing this, be sure that the capacitance is within the stability criteria shown in
Figure 15, Figure 16, and Figure 17.
To not exceed the maximum cathode current, be sure that the supply voltage is current limited. Also, limit the
current being driven into the Ref pin, as not to exceed its absolute maximum rating.
For applications shunting high currents, pay attention to the cathode and anode trace lengths, adjusting the width
of the traces to have the proper current density.
11 Layout
11.1 Layout Guidelines
Place decoupling capacitors as close to the device as possible. Use appropriate widths for traces when shunting
high currents to avoid excessive voltage drops.
