Description and Introduction

Adjustable/2.5V, 0.5% Tolerance Shunt Regulator The LM431CIM is a precision programmable shunt regulator manufactured by Texas Instruments.  

### **Specifications:**  
- **Output Voltage Range:** 2.5V to 36V  
- **Reference Voltage:** 2.495V (Typical)  
- **Operating Current Range:** 1mA to 100mA  
- **Tolerance:** ±0.5%, ±1%, ±2% (depending on variant)  
- **Temperature Stability:** 6mV (Typical) over full temperature range  
- **Package:** 8-Pin SOIC (Small Outline Integrated Circuit)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The LM431CIM is a three-terminal adjustable shunt regulator with thermal stability and low output impedance. It is commonly used in voltage regulation, switching power supplies, and precision voltage references.  

### **Features:**  
- **Adjustable Output Voltage** (via external resistors)  
- **Low Dynamic Output Impedance:** 0.2Ω (Typical)  
- **Low Output Noise**  
- **Fast Turn-On Response**  
- **Wide Operating Current Range** (1mA to 100mA)  
- **Low Temperature Coefficient**  
- **Sink Current Capability:** Up to 100mA  

This device is widely used in applications requiring stable voltage references, such as power supplies, battery chargers, and voltage monitoring circuits.
