Description and Introduction

Precision Micropower Series Voltage Reference The LM4128DQ1MF3.0 is a precision voltage reference manufactured by Texas Instruments (not National Semiconductor, as it was acquired by TI).  

### **Specifications:**  
- **Output Voltage:** 3.0V  
- **Initial Accuracy:** ±0.2%  
- **Temperature Coefficient (Max):** 50 ppm/°C  
- **Operating Temperature Range:** -40°C to +125°C  
- **Output Current:** 10 mA  
- **Supply Voltage Range:** 4V to 12V  
- **Package:** SOT-23-5  
- **Long-Term Stability:** 50 ppm (1000 hours)  
- **Low Dropout Voltage:** 300 mV (typical)  

### **Descriptions:**  
- The LM4128 is a high-precision, low-dropout voltage reference with excellent temperature stability and low noise.  
- It is designed for applications requiring stable voltage references, such as data converters, power supplies, and instrumentation.  
- The device features a low quiescent current and is available in multiple output voltages.  

### **Features:**  
- **High Accuracy:** ±0.2% initial voltage tolerance  
- **Low Noise:** 35 µVpp/V (typical)  
- **Low Dropout Operation:** 300 mV  
- **Low Quiescent Current:** 150 µA (typical)  
- **AEC-Q100 Qualified** for automotive applications  
- **Stable with Capacitive Loads** up to 10 µF  
- **Reverse Battery Protection**  

This device is commonly used in precision analog circuits, battery-powered systems, and industrial control applications.
