Application Environments
This chip is frequently used in:
1. Power Supply Regulation: For precise voltage control.
2. Voltage Monitoring in Safety Systems: Ensuring voltage levels remain within safe limits.
3. Reference Source in Test and Measurement Equipment: Providing accurate benchmark voltages.
Characteristic Parameters
Notable features of the TL431ACLPREG include:
- Variable Output Voltage Range: Adjustable between 2.5 and 36 volts.
- Stable Operation Across Temperature Variations: Consistent performance in different thermal environments.
- Efficient Noise Suppression: Beneficial in sensitive electronic systems.
Application Circuit: Power Supply Regulation
A practical implementation of the TL431ACLPREG in a power supply regulation circuit is described below.
1. Essential Circuit Components
- TL431ACLPREG shunt regulator
- Voltage-setting resistors (R1, R2)
- Basic power supply circuit elements
2. Pin Layout
- Pin 1: Reference (Ref)
- Pin 2: Anode
- Pin 3: Cathode
3. Circuit Assembly Guide
- R1 is connected from the Ref (Pin 1) to the Anode (Pin 2).
- R2 is connected from the Ref (Pin 1) to the Cathode (Pin 3), which also serves as the output.
4. Setting the Output Voltage
- The formula Vout = Vref * (1 + R1/R2) is used to calculate R1 and R2 for the desired output voltage.
5. Design Considerations
- Voltage Regulation Stability: Ensure the circuit maintains a stable voltage under varying loads.
- Thermal Considerations: Be aware of the TL431ACLPREG's temperature, especially in high current settings.
- Precision of Components: Select resistors with low tolerance for greater accuracy in voltage regulation.
6. Output Voltage Calibration
- Adjust R1 and R2 values to fine-tune the output voltage as needed.
Circuit Design Factors
Designing with the TL431ACLPREG requires consideration of its maximum cathode current, the impact of ambient temperatures on its functioning, load stability, and the accuracy of the resistors used.
In summary, the TL431ACLPREG is an adjustable precision shunt regulator used predominantly in power supply regulation, voltage monitoring in safety systems, and as a reference in test equipment. Its key attributes include an adjustable output voltage range, temperature stability, and low noise. Design considerations involve voltage regulation stability, thermal considerations, and component precision.
