Description and Introduction

Improved Precision Micropower Shunt Voltage Reference with Multiple Reverse Breakdown Voltages The LM4040DEX3-3.0+T is a precision voltage reference manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 3.0V  
- **Initial Accuracy:** ±0.1% (A grade), ±0.2% (B grade)  
- **Temperature Coefficient:** 50 ppm/°C (A grade), 100 ppm/°C (B grade)  
- **Operating Current Range:** 60 µA to 15 mA  
- **Output Noise (10 Hz to 10 kHz):** 35 µV (typical)  
- **Package:** SOT-23-3  
- **Operating Temperature Range:** -40°C to +125°C  
- **Load Regulation:** 0.15 mV/mA (typical)  
- **Line Regulation:** 0.2 mV/V (typical)  

### **Descriptions:**
- The LM4040 is a precision two-terminal shunt voltage reference.  
- It provides a fixed output voltage of 3.0V with high accuracy and low temperature drift.  
- Designed for space-constrained applications due to its small SOT-23-3 package.  
- Suitable for analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and power supply regulation.  

### **Features:**
- **Low Dropout Operation:** Works with minimal headroom voltage.  
- **Wide Operating Current Range:** 60 µA to 15 mA.  
- **Low Output Noise:** Ensures stable voltage reference for sensitive circuits.  
- **No External Capacitor Required:** Stable without additional compensation.  
- **Reverse Breakdown Protection:** Enhanced reliability in circuit designs.
