Description and Introduction

Low-Voltage (1.24V) Adjustable Precision Shunt Regulators The LMV431CZ is a low-voltage adjustable precision shunt regulator manufactured by National Semiconductor (now part of Texas Instruments).  

### **Key Features:**  
- **Adjustable Output Voltage:** Can be set from **1.24V to 6V** using external resistors.  
- **Low Operating Voltage:** Works down to **1.24V**, making it suitable for low-voltage applications.  
- **Low Reference Current:** Typical **60µA** for improved efficiency.  
- **High Accuracy:** **±1%** reference voltage tolerance.  
- **Wide Operating Current Range:** **60µA to 15mA**.  
- **Low Dynamic Impedance:** **0.4Ω (typical)** for stable regulation.  
- **Temperature Range:** **-40°C to +85°C**.  
- **Package:** **SOT-23-3** (small form factor).  

### **Applications:**  
- Voltage regulation in portable devices.  
- Battery-powered systems.  
- Power management circuits.  
- Precision voltage references.  

This device is designed for cost-sensitive, low-voltage applications requiring high accuracy and stability.
