TL431CDG4 Typical application Circuitry
The TL431CDG4 is a programmable precision shunt voltage regulator, widely used in various electronic circuits for providing a stable reference voltage. It functions similarly to an adjustable Zener diode but offers superior stability and precision. Key features of the TL431CDG4 include:
1. Adjustable Output Voltage: It can be programmed to provide an output voltage typically ranging from 2.5V to 36V.
2. Low Dynamic Output Impedance: Ensures stable voltage regulation even under changing load conditions.
3. Temperature Stability: Offers consistent performance across a broad temperature range.
4. Wide Operating Current Range: Suitable for a variety of applications due to its broad operational current range.
An application scenario for the TL431CDG4 is in a Linear Power Supply:
- Objective: To utilize the TL431CDG4 for creating a stable output voltage reference in a linear power supply circuit.
1. Reference Voltage Configuration: Connect the anode (A, Pin 1) of the TL431CDG4 to the ground of the circuit.
2. Adjusting the Output Voltage: Link the cathode (K, Pin 3) to the output through a resistor (R1). This resistor helps set up the desired voltage reference point.
3. Feedback Loop: Connect another resistor (R2) from the REF pin (Pin 2) to the ground. The output voltage is determined by the formula Vout = Vref (1 + R2/R1) + Iref * R2.
4. Fine-Tuning Output Voltage: Adjust R1 and R2 to set the desired output voltage as required for the power supply.
5. Stabilizing Capacitors: Place a decoupling capacitor near the REF pin of the TL431CDG4 to stabilize the output and reduce noise.
Design considerations when using the TL431CDG4 include:
- Precision of Resistors: Use high-precision resistors for R1 and R2 to ensure accurate setting of the output voltage.
- Thermal Management: Consider the temperature coefficient of the TL431CDG4 and the resistors to maintain voltage stability across temperature variations.
- Noise Reduction: Put techniques in place to reduce circuit noise, which is particularly important in applications involving power supplies.
- Load Regulation: Ensure that the circuit can handle changes in load without affecting the stability of the output voltage.
In summary, the TL431CDG4 is a highly versatile and precise shunt voltage regulator, ideal for applications like linear power supply circuits where stable and adjustable voltage regulation is essential. Key design considerations include using precision resistors, managing thermal effects, reducing noise, and ensuring load regulation.
