Description and Introduction

Programmable Precision References The TL431AILPG is a programmable precision shunt regulator manufactured by ON Semiconductor.  

### **Specifications:**  
- **Output Voltage Range:** 2.495V to 36V (adjustable)  
- **Reference Voltage:** 2.495V (typical)  
- **Operating Cathode 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 (3-lead)  

### **Descriptions:**  
- The TL431AILPG is a three-terminal adjustable shunt regulator with guaranteed thermal stability.  
- It provides precise voltage references and can be used in switching power supplies, voltage monitoring, and error amplifiers.  
- The device features low dynamic output impedance and sharp turn-on characteristics.  

### **Features:**  
- Adjustable output voltage with two external resistors  
- Low output noise  
- Fast turn-on response  
- Low temperature drift  
- High accuracy (0.5%, 1%, and 2% voltage reference options)  
- Wide operating current range (1mA to 100mA)
