Description and Introduction

Low-Voltage Adjustable Precision Shunt Regulator The TLVH431AIDCKR is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Output Voltage Range:** 1.24V to 6V  
- **Reference Voltage:** 1.24V (typical)  
- **Operating Current (I_KA):** 80µA (typical)  
- **Accuracy:** ±1% (A-grade)  
- **Temperature Range:** -40°C to +125°C  
- **Package:** SC-70 (DCK), 6-pin  
- **Cathode Current Range (I_KA):** 1mA to 70mA  
- **Low Dynamic Output Impedance:** 0.25Ω (typical)  

### **Descriptions:**  
The TLVH431AIDCKR is a three-terminal adjustable shunt regulator with thermal stability and low operating current. It is designed for precision voltage reference and regulation applications, including power supplies, battery chargers, and voltage monitoring circuits.  

### **Features:**  
- Adjustable output voltage (1.24V to 6V)  
- Low operating current (80µA typical)  
- High accuracy (±1%)  
- Stable with capacitive loads  
- Low output impedance (0.25Ω typical)  
- Wide operating temperature range (-40°C to +125°C)  
- Small SC-70 package for space-constrained designs  

This device is commonly used in portable electronics, power management, and precision voltage regulation applications.
