Description and Introduction

Low-Voltage Adjustable Precision Shunt Regulator The TLVH431QDBZR is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Output Voltage Range:** 1.24V to 6V  
- **Reference Voltage:** 1.24V (typical)  
- **Operating Current Range:** 80µA to 15mA  
- **Sink Current Capability:** Up to 20mA  
- **Initial Accuracy (TLVH431A):** ±0.5%  
- **Initial Accuracy (TLVH431B):** ±1%  
- **Temperature Stability:** 6mV (typical) over full temperature range  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-3 (DBZ)  

### **Descriptions:**
- The TLVH431QDBZR is a low-voltage version of the TL431 shunt regulator, designed for precision voltage reference and regulation applications.  
- It is adjustable via external resistors, making it suitable for various low-voltage circuits.  
- It operates with a lower minimum cathode current (80µA) compared to standard shunt regulators.  
- The device is available in two grades (A and B) with different initial voltage accuracies.  

### **Features:**
- **Low-Voltage Operation:** Supports adjustable output down to 1.24V.  
- **Low Operating Current:** As low as 80µA, improving efficiency in battery-powered applications.  
- **High Accuracy:** Tight reference voltage tolerance (±0.5% for A grade).  
- **Wide Temperature Range:** Operates reliably from -40°C to +125°C.  
- **Small Package:** SOT-23-3 footprint for space-constrained designs.  
- **Improved Stability:** Low output impedance and temperature drift.  

This information is strictly based on the manufacturer's datasheet and technical documentation.
