TLV431AIDBVRE4 Typical application Circuitry

TLV431AIDBVRE4

The TLV431AIDBVRE4 is a precision low-voltage shunt regulator. Here's a detailed breakdown of its functionality, applications, key parameters, and a specific application circuit design:

Functionality of TLV431AIDBVRE4:

- Adjustable Output Voltage: It can be programmed from the reference voltage (Vref) up to 18 V with two external resistors.

- Low Dynamic Output Impedance: Ensures stability and good transient response.

- Precision Reference Voltage: Offers a typical reference voltage of 1.24 V.

- Low Operational Current: Ideal for battery-powered devices.

Application Scenarios:

- Voltage Reference in Power Supplies

- Battery Chargers

- Switching Power Supplies

- Voltage Monitoring in Automotive and Industrial Systems

Key Parameter Features:

- Reference Voltage Tolerance: ±0.5% at 25°C, ±2.5% over full temperature range.

- Maximum Cathode Current: Typically 15 mA.

- Low Minimum Cathode Voltage: Around 1.24 V for adequate regulation.

- Temperature Range: Operates efficiently across a wide range of temperatures.

Application Circuit Design – Adjustable Voltage Power Supply:

1. Selecting Components:

- R1 & R2 for Voltage Setting: Choose values to set the desired output voltage.

- Capacitors: Add stability and filter noise.

2. Connecting to the Chip:

- Pin 1 (Anode): Connect to the ground.

- Pin 2 (Reference): Attach to the junction of R1 and R2.

- Pin 3 (Cathode): Connect to the output voltage node.

3. Adjusting the Output Voltage:

- Formula: Vout = Vref(1 + R2/R1) + Iref*R2.

- Adjust R1 and R2: To achieve the desired Vout.

4. Stability Considerations:

- Bypass Capacitor: Place close to the Reference pin for noise reduction.

5. Heat Dissipation:

- Heat Sink: If the power dissipation is high, consider a heat sink for the TLV431AIDBVRE4.

Design Considerations:

- Load Regulation: Ensure the circuit can handle changes in load.

- Thermal Considerations: Monitor junction temperature.

- Transient Response: Minimize output voltage fluctuations during load and line changes.

In designing circuits with the TLV431AIDBVRE4, it's crucial to understand its electrical characteristics and how they align with the specific requirements of your application. Adjusting component values and ensuring proper thermal management are key aspects to consider for efficient and reliable operation.
