Description and Introduction

2.048 V, improved precision micropower shunt voltage reference with multiple reverse breakdown voltage The LM4040CIM3-2.1-T is a precision voltage reference manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 2.1V (fixed)  
- **Initial Accuracy:** ±0.1% (A-grade), ±0.2% (B-grade)  
- **Temperature Coefficient (Tempco):** 50ppm/°C (A-grade), 100ppm/°C (B-grade)  
- **Operating Current Range:** 60µA to 12mA  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-3  
- **Output Current:** Up to 15mA  
- **Line Regulation:** 0.05mV/mA (typical)  
- **Load Regulation:** 0.2mV/mA (typical)  

### **Descriptions:**
- The LM4040 is a shunt voltage reference that provides a stable 2.1V output.  
- It is designed for precision applications requiring low power consumption and high accuracy.  
- Available in multiple voltage options (e.g., 1.225V, 2.048V, 2.5V, 3V, 4.096V, 5V).  

### **Features:**
- **Low Dropout Voltage:** Operates down to 1V above the reference voltage.  
- **Low Noise:** 35µVrms (typical) over 10Hz to 10kHz.  
- **Wide Operating Current Range:** 60µA to 12mA.  
- **Stable with Capacitive Loads:** No external capacitor required.  
- **AEC-Q100 Qualified:** Available for automotive applications.  

This part is commonly used in precision analog circuits, data converters, power supplies, and battery-powered devices.
