Description and Introduction

Adjustable Precision Shunt Regulator The TS431A is a precision shunt voltage reference manufactured by STMicroelectronics. Below are the factual details about its specifications, descriptions, and features:

### **Specifications:**  
- **Reference Voltage:** 2.495V (typical)  
- **Voltage Tolerance:** ±0.5%, ±1%, ±2% (depending on variant)  
- **Operating Current Range:** 80µA to 100mA  
- **Sink Current Capability:** Up to 100mA  
- **Temperature Range:** -40°C to +125°C  
- **Low Dynamic Impedance:** 0.22Ω (typical)  
- **Package Options:** SOT-23, SOT-323, TO-92  

### **Descriptions:**  
The TS431A is an adjustable precision shunt regulator that provides a stable voltage reference. It is commonly used in power supplies, battery chargers, and voltage monitoring circuits. The device operates similarly to a Zener diode but with better accuracy and stability.  

### **Features:**  
- **Adjustable Output Voltage** (via external resistors)  
- **Low Output Noise**  
- **Wide Operating Current Range**  
- **High Accuracy** (±0.5% for A-grade)  
- **Stable Over Temperature and Load Variations**  
- **AEC-Q100 Qualified** (for automotive applications)  

This information is sourced from the official STMicroelectronics datasheet for the TS431A.
