- **Reference Voltage (Vref):** 1.24V (typical)  
- **Operating Current (I_KA):** 80µA (typical)  
- **Sink Current Capability:** 1mA to 100mA  
- **Accuracy:** 0.5%, 1%, or 2% (depending on grade)  
- **Temperature Range:** -40°C to +125°C  
- **Package Options:** SOT-23, SC-70, SOT-89, TO-92  

### **Descriptions:**  
The TLV431B is a three-terminal adjustable shunt regulator with thermal stability and low operating current. It is designed for applications requiring precision voltage references, such as power supplies, battery chargers, and voltage monitoring circuits.  

### **Features:**  
- Adjustable output voltage with two external resistors  
- Low operating current (80µA typical)  
- Wide operating temperature range (-40°C to +125°C)  
- Low output impedance (0.25Ω typical)  
- Stable with low-ESR capacitors (≥0.1µF)  
- Available in multiple accuracy grades (0.5%, 1%, 2%)  
- Improved alternative to the TL431 with lower voltage operation  

For detailed electrical characteristics, refer to the official TI datasheet.
