Description and Introduction

Low-Voltage Adjustable Precision Shunt Regulator The TLVH431IDCKR 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 Range:** 80µA to 15mA  
- **Low Operating Cathode Current:** 80µA (typical)  
- **Accuracy:** 0.5% (A grade), 1% (B grade)  
- **Temperature Range:** -40°C to +125°C  
- **Package:** SC-70 (DCK), 5-pin  
- **Output Sink Current Capability:** 1mA to 70mA  

### **Descriptions:**  
The TLVH431IDCKR is a low-voltage, adjustable shunt regulator with a precision reference voltage. It is designed for applications requiring tight voltage regulation and low power consumption. It can be used as a replacement for the TL431 in low-voltage applications.  

### **Features:**  
- Adjustable output voltage with two external resistors  
- Low-voltage operation (down to 1.24V)  
- Low quiescent current (80µA typical)  
- Stable with low-ESR capacitors (≥0.47µF)  
- Available in A (0.5%) and B (1%) voltage tolerance grades  
- Small SC-70 package for space-constrained applications  

This device is commonly used in power supplies, battery-operated systems, and voltage monitoring circuits.
