Description and Introduction

Precision Micropower Shunt Voltage Reference The **LM4041BIM3X-1.2** is a precision voltage reference manufactured by **National Semiconductor** (now part of Texas Instruments). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 1.225V (fixed)  
- **Tolerance:** ±0.1% (A grade), ±0.2% (B grade)  
- **Operating Current Range:** 60µA to 12mA  
- **Temperature Coefficient:** 100ppm/°C (max)  
- **Package:** SOT-23 (3-pin)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Line Regulation:** 0.05%/V (typ)  
- **Load Regulation:** 0.1%/mA (typ)  

### **Description:**
The LM4041BIM3X-1.2 is a shunt voltage reference that provides a stable **1.225V** output. It is designed for precision applications requiring low power consumption and high accuracy. The device operates without an external capacitor, ensuring stability.

### **Features:**
- **Low Dropout Voltage:** Works with minimal headroom.  
- **Low Quiescent Current:** 60µA (typ).  
- **No External Capacitor Required:** Stable without additional components.  
- **High Output Accuracy:** Tight tolerances (±0.1% or ±0.2%).  
- **Wide Operating Current Range:** 60µA to 12mA.  
- **Small Form Factor:** SOT-23 package for space-constrained designs.  

This part is commonly used in **ADCs, DACs, power supplies, and battery-powered devices** where precise voltage references are critical.
