Frequently Asked Questions (FAQ)

  • Q: Where can I find a circuit for the TL431 Shunt Regulator switch?

    A: One simple way to protect circuits from over voltage is the use of a Shunt Regulator IC TL431 to switch off the load if the voltage increases above the preset level. In unregulated power supply, if the voltage in the primary of the step down transformer increases, a corresponding increase in voltage will appears in the secondary also. This may seriously affect the circuit, if it uses voltage sensitive semiconductors.TL431 is an adjustable precision Zener shut regulator and its output voltage can be set between 2.5 volts to 36 volts using a voltage divider. It can functions like a Zener diode but with precision. more

  • Q: Where can I find TL431 application notes?

    A: 2% Accuracy Adjustable Precision Shunt Regulator more

  • Q: How can I calculate the values for TL431 shunt regulator?

    A: TL431 Calculator more

  • Q: Where can I find a TL431 pinout diagram?

    A: The TL431 and TL432 devices are three-terminal adjustable shunt regulators, with specified thermal stability over applicable automotive, commercial, and military temperature ranges. The output voltage can be set to any value between Vref (approximately 2.5 V) and 36 V, with two external resistors (see ). These devices have a typical output impedance of 0.2 Ω. Active output circuitry provides a very sharp turn-on characteristic, making these devices excellent replacements for Zener diodes in many applications, such as onboard regulation, adjustable power supplies, and switching power supplies. The TL432 device has exactly the same functionality and electrical specifications as the TL431 device, but has different pinouts for the DBV, DBZ, and PK packages. more

  • Q: Where can I find a TL431 voltage regulator circuit?

    A: The TL431 is a reference voltage source that is commonly used in the control circuit of isolated power supplies. Typically used to provide a precision reference voltage, the TL431 can also be configured as an analog controller by exploiting its on-board error amplifier. In this example, the design of a TL431-based type 2 voltage controller for a flyback converter is presented. The voltage control circuit regulates the output voltage of the 5 V winding and includes an optocoupler to maintain isolation between the input and output stages. The example circuit is shown below. more

  • Q: How do I use a TL431 shunt regulator?

    A: This is the Shunt Regulator circuitwith TL431 Voltage Reference – Shunt Voltage Reference IC. They is easy to used,comprises one IC, three resistors, four capacitors.if you like to use zener diode for the voltage reference,it very cheap but low quality than the IC. In circuit the output is 5volt 15mA, if you other voltage can change R2,R2. The C1,C2,C3 use for filter the volt,low noise ripple. more

  • Q: Where can I download a TL431 Spice model?

    A: TL431 is commonly used to create a voltage reference or small linear shunt regulator. It is often considered to be a “programmable zener”. Though, there is a big difference betweenTL431 and a zener diode. As many of other feedback systems, TL431 can oscillate if inappropriately decoupled. more

  • Q: How do I use the TL431 as an LDO regulator?

    A: Given the vast number of application notes, design guides and other material concerning low dropout (LDO) regulators, anyone would think they were complex. Despite initial appearances, they actually are complex. There are many things that must be considered to ensure stability, and not the least of these is due to the use of a PNP series pass transistor or a P-Channel MOSFET, which means the output is from the collector or drain, and not the emitter or source as with most conventional regulators. more

  • Q: How do I use the TL431 for low voltage cutoff?

    A: The cutoff point is set by the ratio of R2 and R3. 6V is appropriate for a 7 cell Nicad or 2 cell Li-ion pack, 7.2V for an 8 cell Nicad, and 9V for a 3 cell Li-ion battery. Resistors R2 and R3 should be 1% tolerance for accuracy. Alternatively, a variable resistor could be used to adjust the cutoff voltage. more

  • Q: Where can I find a circuit diagram for TL431 overvoltage protection?

    A: The TL431 device has three terminals and main application of this device is adjustable shunt regulation. The reference regulating voltage can be given through cathode and reference pin. Here the VR1 variable resistor decides the regulation range, by changing it we can get different range of regulating voltage. more
