Description and Introduction

3-V Precision Micropower Shunt Voltage Reference, 0.5% accuracy The LM4040C30IDBZR is a precision voltage reference manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 3.0V  
- **Initial Accuracy:** ±0.1% (max)  
- **Temperature Coefficient (Tempco):** 50 ppm/°C (max)  
- **Operating Current Range:** 60 µA to 15 mA  
- **Output Voltage Tolerance:** ±0.1%, ±0.2%, ±0.5%, ±1% (depending on grade)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23 (DBZ)  

### **Descriptions:**
- The LM4040 is a precision two-terminal shunt voltage reference.  
- It provides a fixed output voltage with high accuracy and low temperature drift.  
- Available in multiple voltage options (1.225V to 10V), with the LM4040C30IDBZR specifically providing 3.0V.  
- Designed for space-constrained applications due to its small SOT-23 package.  

### **Features:**
- **Low Dropout Operation:** Works with minimal headroom voltage.  
- **Low Noise:** Ensures stable voltage reference performance.  
- **Wide Operating Current Range:** 60 µA to 15 mA.  
- **No External Capacitor Required:** Stable without additional components.  
- **AEC-Q100 Qualified:** Suitable for automotive applications.  
- **Reverse Breakdown Protection:** Enhances reliability.  

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