Description and Introduction

Adjustable Precision Zener Shunt Regulator The LM431CIM3 is a precision programmable shunt regulator manufactured by National Semiconductor (NSC). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** National Semiconductor (NSC)  
- **Part Number:** LM431CIM3  
- **Package:** SOT-23 (3-Lead)  
- **Type:** Adjustable Precision Shunt Regulator  
- **Reference Voltage:** 2.495V (Typical)  
- **Voltage Range (Cathode to Anode):** 2.5V to 36V  
- **Output Current Range:** 1mA to 100mA  
- **Temperature Stability:** ±0.4% (Typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Tolerance:** 0.5%, 1%, and 2% (Depending on Variant)  

### **Descriptions:**  
The LM431CIM3 is a 3-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 to any value between 2.5V and 36V with two external resistors.  

### **Features:**  
- **Adjustable Output Voltage** (Vref = 2.495V)  
- **Low Dynamic Output Impedance:** 0.2Ω (Typical)  
- **Sink Current Capability:** 1mA to 100mA  
- **Low Output Noise**  
- **Fast Turn-On Response**  
- **Wide Operating Temperature Range** (-40°C to +85°C)  
- **Available in SOT-23 Package** (Space-Saving)  

This information is strictly based on the manufacturer's datasheet and specifications.
