- **Load Regulation:** 0.05 mV/mA (typical)  

### **Descriptions:**  
- The LM4041 is a precision two-terminal shunt voltage reference.  
- It provides a fixed 1.2V output with low noise and high stability.  
- Designed for space-constrained applications due to its small SOT-23 package.  

### **Features:**  
- **Low Dropout Operation:** Works with minimal headroom.  
- **Low Noise:** Suitable for precision analog circuits.  
- **No External Capacitor Required:** Stable without additional components.  
- **Wide Operating Current Range:** Supports low-power and higher-current applications.  
- **Reverse Breakdown Voltage Options:** Available in multiple fixed voltages (1.2V, 2.048V, 2.5V, 3V, 4.096V, 5V).  

This device is commonly used in ADCs, DACs, power supplies, and battery-powered systems requiring stable voltage references.
