Description and Introduction

LOW VOLTAGE ADJUSTABLE SHUNT REFERENCE The TS431I is a precision shunt voltage reference manufactured by STMicroelectronics (ST). Below are the factual details about its specifications, descriptions, and features:

### **Specifications:**  
- **Output Voltage (Vref):** 2.495V (typical)  
- **Tolerance:** ±0.5%, ±1%, ±2% (depending on variant)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Supply Voltage Range (Cathode to Anode):** 1.24V to 18V  
- **Quiescent Current (Iq):** 80µA (typical)  
- **Sink Current Capability:** 1mA to 100mA  
- **Output Impedance:** 0.2Ω (typical)  
- **Package Options:** SOT23-3, SOT323-3, SOT23-5  

### **Descriptions:**  
The TS431I is a three-terminal adjustable precision shunt regulator with thermal stability and low dynamic impedance. It is designed to replace Zener diodes in applications requiring high precision. The device operates as a stable voltage reference when biased with a current source and a resistor.  

### **Features:**  
- **Low Voltage Operation:** Down to 1.24V  
- **High Accuracy:** ±0.5% voltage tolerance  
- **Low Output Noise**  
- **Wide Operating Current Range:** 1mA to 100mA  
- **Low Temperature Drift:** 50ppm/°C (typical)  
- **AEC-Q100 Qualified** (for automotive applications)  
- **ESD Protection:** Up to 2kV (HBM)  

This information is based on the manufacturer's datasheet and technical documentation.
