Description and Introduction

PROGRAMMABLE PRECISION REFERENCES The TL431BIP is a precision programmable shunt regulator manufactured by Texas Instruments. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Reference Voltage:** 2.495V (Typical)  
- **Adjustable Output Voltage:** 2.5V to 36V  
- **Operating Cathode Current Range:** 1mA to 100mA  
- **Output Impedance:** 0.2Ω (Typical)  
- **Temperature Stability:** ±4mV (0°C to 70°C)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** PDIP-8 (Plastic Dual In-Line Package)  

### **Descriptions:**  
- The TL431BIP is a three-terminal adjustable shunt regulator with thermal stability.  
- It provides precise voltage references for switching power supplies, voltage regulators, and other applications requiring stable voltage references.  
- The device operates as a low-temperature-coefficient Zener diode with programmable voltage.  

### **Features:**  
- **Adjustable Output Voltage** via external resistors.  
- **Low Dynamic Output Impedance** (0.2Ω typical).  
- **Wide Operating Cathode Current Range** (1mA to 100mA).  
- **Low Output Noise Voltage**.  
- **Fast Turn-On Response**.  
- **High Stability Over Temperature and Current Variations**.  
- **Available in Industrial-Grade Temperature Range** (-40°C to +125°C).  

This information is based solely on manufacturer-provided data.
