Description and Introduction

Voltage Reference The TL431BCLP is a programmable precision voltage reference manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Reference Voltage (Vref):** 2.495V (Typical)  
- **Operating Cathode Current (IK):** 1mA to 100mA  
- **Output Voltage Range:** 2.5V to 36V  
- **Temperature Stability:** 50ppm/°C (Typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** TO-92 (LP)  

### **Descriptions:**  
The TL431BCLP is a three-terminal adjustable shunt regulator with thermal stability. It provides precise voltage references and can be used in switching power supplies, voltage monitoring, and error amplifiers.  

### **Features:**  
- **Adjustable Output Voltage** (via external resistors)  
- **Low Dynamic Output Impedance:** 0.2Ω (Typical)  
- **Sink Current Capability:** Up to 100mA  
- **Low Output Noise**  
- **Wide Operating Cathode Current Range** (1mA to 100mA)  
- **Equivalent to Industry Standard TL431**  

This information is based on TI's official datasheet for the TL431BCLP.
