Description and Introduction

50ppm/°C Precision Micropower Shunt Voltage References with Multiple Reverse Breakdown Voltages The LM4050AIM3-4.1 is a precision voltage reference manufactured by National Semiconductor (now part of Texas Instruments).  

### **Specifications:**  
- **Output Voltage:** 4.096V (±0.1% initial accuracy)  
- **Operating Current Range:** 60µA to 15mA  
- **Temperature Coefficient:** 20ppm/°C (typical)  
- **Output Voltage Tolerance:** ±0.1% (A grade)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-3  
- **Long-Term Stability:** 20ppm/1000hrs (typical)  
- **Line Regulation:** 0.05mV/V (typical)  
- **Load Regulation:** 0.1mV/mA (typical)  

### **Descriptions and Features:**  
- **Precision Shunt Voltage Reference**  
- Low dropout operation (1µA minimum cathode current)  
- **Low Noise:** 35µVrms (10Hz to 10kHz)  
- **Wide Operating Current Range** (60µA to 15mA)  
- **Reverse Breakdown Voltage Options** (1.225V to 5.0V)  
- **No External Capacitor Required** for stability  
- **Industrial and Automotive Applications**  
- **AEC-Q100 Qualified** (for automotive applications)  

This device is commonly used in precision analog circuits, data converters, power supplies, and battery-powered systems requiring stable voltage references.  

(Note: National Semiconductor was acquired by Texas Instruments in 2011, but legacy part numbers remain in use.)
