Description and Introduction

Improved Precision Micropower Shunt Voltage Reference The **LM4041CEX3-1.2+T** is a precision voltage reference manufactured by **Maxim Integrated** (now part of Analog Devices). Below are its key specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Output Voltage:** 1.225V (fixed)  
- **Initial Accuracy:** ±0.1% (max)  
- **Temperature Coefficient:** 100ppm/°C (max)  
- **Operating Current Range:** 45µA to 12mA  
- **Output Voltage Tolerance:** ±0.1%, ±0.2%, ±0.5%, ±1% (selectable by suffix)  
- **Package:** SOT-23-3  
- **Operating Temperature Range:** -40°C to +85°C  
- **Load Regulation:** 0.2mV/mA (typ)  
- **Line Regulation:** 0.05mV/V (typ)  

### **Descriptions:**  
- The **LM4041CEX3-1.2+T** is a shunt voltage reference with a fixed output voltage of **1.225V**, designed for precision applications.  
- It operates like a Zener diode but with improved stability and accuracy.  
- Suitable for low-power devices due to its low quiescent current (45µA min).  
- Offered in a **SOT-23-3** package for space-constrained applications.  

### **Features:**  
- **Low Dropout Operation:** Works with minimal headroom voltage.  
- **Low Noise:** Optimized for precision analog circuits.  
- **Wide Operating Current Range:** 45µA to 12mA.  
- **High Accuracy:** Tight initial tolerances (±0.1% max).  
- **Stable Over Temperature:** Low temperature coefficient (100ppm/°C max).  
- **No External Capacitor Required:** Stable without additional components.  

This information is strictly based on the manufacturer's datasheet and specifications.
