Description and Introduction

Precision Micropower Shunt Voltage Reference The LM4040AIM3X-2.5 is a precision voltage reference manufactured by Texas Instruments (formerly National Semiconductor, NS).  

### **Specifications:**  
- **Output Voltage:** 2.5V  
- **Initial Accuracy:** ±0.1% (A-grade)  
- **Temperature Coefficient:** 50 ppm/°C (typical)  
- **Operating Current Range:** 60 µA to 15 mA  
- **Package:** SOT-23-3  
- **Operating Temperature Range:** -40°C to +85°C  
- **Line Regulation:** 0.05 mV/V (typical)  
- **Load Regulation:** 0.1 mV/mA (typical)  
- **Long-Term Stability:** 20 ppm/1000 hours (typical)  

### **Descriptions:**  
- The LM4040 is a precision two-terminal shunt voltage reference.  
- It offers excellent temperature stability and low noise.  
- Available in fixed reverse breakdown voltages of 2.048V, 2.5V, 3V, 4.096V, 5V, 8.192V, and 10V.  
- The device operates as a shunt regulator, requiring only an external resistor for operation.  

### **Features:**  
- Low output noise (35 µVrms, 10 Hz to 10 kHz)  
- No output capacitor required for stability  
- Wide operating current range (60 µA to 15 mA)  
- High output current capability (15 mA)  
- Low dynamic impedance (0.25 Ω typical)  
- AEC-Q100 qualified for automotive applications (certain versions)  

This information is based solely on the manufacturer's datasheet.
