The TL431ACLPR5 is typically used in:
1. Power Supply Stabilization: For regulating output voltages.
2. Under-voltage or Over-voltage Detection: In safety and protection circuits.
3. Reference Voltage in Control Systems: Providing accurate and stable voltages for control mechanisms.
Parameter Features
The TL431ACLPR5 is characterized by:
- Variable Output Voltage Range: Adjustable from 2.5 to 36 volts.
- Consistent Operation Across Temperature Variations: Maintaining performance in different thermal environments.
- Low Noise Characteristics: Suitable for precision and noise-sensitive applications.
Application Circuit: Under-voltage Detection
Here is a detailed application of the TL431ACLPR5 in an under-voltage detection circuit.
1. Key Circuit Components
- TL431ACLPR5 shunt regulator
- Voltage-setting resistors (R1, R2)
- Under-voltage detection circuit elements
2. Pin Configuration
- Pin 1: Reference (Ref)
- Pin 2: Anode
- Pin 3: Cathode
3. Circuit Assembly Process
- R1 is connected from Ref (Pin 1) to Anode (Pin 2).
- R2 is linked from Ref (Pin 1) to Cathode (Pin 3), the output terminal.
4. Adjusting Output Voltage
- Use the formula Vout = Vref * (1 + R1/R2) to set R1 and R2 for the desired voltage threshold.
5. Design Consideration Points
- Voltage Threshold Accuracy: Ensure precise detection of under-voltage conditions.
- Thermal Management: Monitor the TL431ACLPR5's temperature, especially under heavy load.
- Component Selection Accuracy: Select resistors with low tolerance for precise voltage control.
6. Voltage Threshold Calibration
- Fine-tune R1 and R2 to accurately set the under-voltage detection threshold.
Circuit Design Essentials
In designing circuits with the TL431ACLPR5, it's important to consider maximum cathode current, temperature effects on performance, stability under various load conditions, and precision of the resistors.
In summary, the TL431ACLPR5 is a versatile shunt regulator, well-suited for power supply stabilization, under-voltage detection, and as a reference in control systems. It features an adjustable output voltage range, temperature stability, and low noise output. Key design factors include voltage threshold accuracy, thermal management, and component selection accuracy.
