Description and Introduction

Low-Voltage Adjustable Precision Shunt Regulator The TLV431BIDBZR is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Output Voltage Range:** 1.24V to 6V  
- **Reference Voltage (Vref):** 1.24V (typical)  
- **Operating Cathode Current (Ika):** 80µA (minimum) to 100mA (maximum)  
- **Sink Current Capability:** 1mA to 100mA  
- **Initial Accuracy:** 0.5%, 1%, or 2% (depending on grade)  
- **Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-3 (DBZ)  

### **Descriptions:**  
The TLV431BIDBZR is a three-terminal adjustable shunt regulator with thermal stability over the operating temperature range. It is designed for applications requiring low-voltage regulation, such as power supplies, battery chargers, and voltage references.  

### **Features:**  
- Low-voltage operation (down to 1.24V)  
- Adjustable output voltage  
- Low operational cathode current (80µA min)  
- High accuracy (0.5%, 1%, or 2%)  
- Stable with low-ESR capacitors  
- SOT-23-3 package for space-constrained designs  
- AEC-Q100 qualified for automotive applications  

This information is based on the manufacturer's datasheet.

Application Scenarios & Design Considerations

Low-Voltage Adjustable Precision Shunt Regulator

Alternative Part Number

  • LMV431AIM5/NOPB --: Adjustable shunt regulator with similar 1.24V reference and SOT-23-5 package, widely used as a TLV431 alternative.
  • AZ431AN-BTRE1 --: Adjustable shunt regulator with 2.5V reference and SOT-23 package, a common cross-reference for shunt regulator designs.
  • TL431AIDBZR --: Industry-standard adjustable shunt regulator in SOT-23 package; higher reference voltage but often used where TLV431 is unavailable.
  • AP431SAKTR-G1 --: Adjustable precision shunt regulator in SOT-23 with 1.24V reference, suitable replacement when TLV431 availability is limited.
