Description and Introduction

Adjustable Precision Zener Shunt Regulator The LM431AIBPX is a precision programmable shunt regulator manufactured by Texas Instruments (NS).  

### **Specifications:**  
- **Output Voltage Range:** 2.5V to 36V (programmable)  
- **Reference Voltage:** 2.495V (typical)  
- **Operating Current Range:** 1mA to 100mA  
- **Tolerance:** 0.5%, 1%, and 2% options  
- **Temperature Stability:** 6mV (typical) over full temperature range  
- **Package Type:** SOT-23 (3-Pin)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The LM431AIBPX is an adjustable precision voltage reference with excellent thermal stability. It operates as a shunt regulator, providing a stable reference voltage when used with external resistors. It is commonly used in power supplies, voltage monitoring, and precision regulation applications.  

### **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)  
- **Available in High-Accuracy Grades** (0.5%, 1%, 2%)  

This device is suitable for applications requiring stable voltage references, such as switching power supplies, battery chargers, and voltage regulators.
