Description and Introduction

Programmable Shunt Regulator The LM431BCM is a precision programmable shunt regulator manufactured by Fairchild Semiconductor (now part of ON Semiconductor). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Output Voltage Range:** 2.5V to 36V (programmable)  
- **Reference Voltage:** 2.495V (typical)  
- **Operating Current Range:** 1mA to 100mA  
- **Line Regulation:** 0.2% (typical)  
- **Load Regulation:** 0.4% (typical)  
- **Temperature Stability:** ±0.5% (over full temperature range)  
- **Package:** SOIC-8  
- **Operating Temperature Range:** 0°C to +70°C  

### **Descriptions:**  
The LM431BCM is a three-terminal adjustable shunt regulator with thermal stability over the full operating temperature range. It is commonly used in switching power supplies, voltage references, and error amplifiers. The output voltage can be set with two external resistors, making it highly versatile for various applications.  

### **Features:**  
- **Adjustable Output Voltage** (2.5V to 36V)  
- **Low Dynamic Output Impedance** (0.2Ω typical)  
- **Sink Current Capability** (1mA to 100mA)  
- **Low Output Noise**  
- **Fast Turn-On Response**  
- **Wide Operating Temperature Range**  
- **Available in SOIC-8 Package**  

This information is based on Fairchild's datasheet for the LM431BCM.
