Description and Introduction

Adjustable Precision Shunt Regulator 6-SC70 -40 to 85 The TL431AIDCKRG4 is a precision programmable shunt regulator manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Output Voltage Range:** 2.495V to 36V  
- **Reference Voltage Tolerance:** ±1% (A-grade)  
- **Operating Cathode Current Range:** 1mA to 100mA  
- **Temperature Range:** -40°C to +125°C  
- **Package:** SC-70 (SOT-563)  
- **Pin Count:** 6  
- **Adjustable Output Voltage** via external resistors  

### **Descriptions:**  
The TL431AIDCKRG4 is a three-terminal adjustable shunt regulator with thermal stability. It provides precise voltage regulation and can be used as a replacement for Zener diodes in many applications.  

### **Features:**  
- Adjustable output voltage with two external resistors  
- Low dynamic output impedance (0.2Ω typical)  
- Sink current capability up to 100mA  
- Low output noise  
- Fast turn-on response  
- Stable with capacitive loads  

This device is commonly used in power supplies, battery chargers, and voltage monitoring circuits.

Application Scenarios & Design Considerations

Adjustable Precision Shunt Regulator 6-SC70 -40 to 85

Alternative Part Number

  • LM431AIM3 --: Adjustable shunt voltage reference with similar 2.5V reference and tolerance grade, widely used as a TL431 replacement in a different series naming.
  • KA431AZ --: Industry-standard adjustable shunt regulator functionally equivalent to the TL431, available in TO-92 package with comparable reference voltage and current capability.
  • AS431ANTR-G1 --: Low-cost adjustable precision shunt regulator with 2.5V reference, pin-compatible behavior and different series prefix for easy distinction.
