Description and Introduction

PROGRAMMABLE PRECISION REFERENCE The TL431L is a precision programmable shunt regulator manufactured by JRC (New Japan Radio). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Output Voltage Range:** 2.5V to 36V (adjustable)  
- **Reference Voltage:** 2.495V (typical)  
- **Operating Current Range:** 1mA to 100mA  
- **Output Impedance:** 0.2Ω (typical)  
- **Temperature Stability:** ±4mV (over full temperature range)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** TO-92, SOT-23, or other small packages  

### **Descriptions:**  
- The TL431L is a three-terminal adjustable shunt regulator with thermal stability.  
- It is commonly used in power supply feedback circuits, voltage references, and precision regulators.  
- The device operates by comparing an internal reference voltage with an external voltage divider to control current flow.  

### **Features:**  
- **Adjustable Output Voltage:** Can be set using two external resistors.  
- **Low Dynamic Output Impedance:** Ensures stable regulation.  
- **Low Output Noise:** Suitable for precision applications.  
- **Wide Operating Current Range:** Supports a broad range of load conditions.  
- **Low Temperature Coefficient:** Maintains stability across temperature variations.  

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