Description and Introduction

1A Low Dropout Adjustable Regulator 5-TO-220 -40 to 125 The **LM2941T/NOPB** is a low-dropout voltage regulator manufactured by **National Semiconductor (NS)**.

### **Specifications:**
- **Input Voltage Range:** Up to **26V**  
- **Output Voltage Options:** Fixed (5V, 12V, 15V) or Adjustable (1.275V to 20V)  
- **Output Current:** **1A**  
- **Dropout Voltage:** **0.5V (typical) at 1A**  
- **Line Regulation:** **0.3% (typical)**  
- **Load Regulation:** **0.4% (typical)**  
- **Quiescent Current:** **10mA (typical)**  
- **Operating Temperature Range:** **-40°C to +125°C**  
- **Package:** **TO-220-5 (5-pin)**  

### **Descriptions:**  
The LM2941T/NOPB is a **positive voltage regulator** designed to provide a stable output voltage with low dropout, making it suitable for battery-powered applications. It includes **thermal shutdown, current limiting, and reverse battery protection** for enhanced reliability.  

### **Features:**  
- **Low dropout voltage (0.5V typical at 1A)**  
- **Reverse battery protection**  
- **Internal short-circuit current limiting**  
- **Thermal overload protection**  
- **Adjustable or fixed output voltage options**  
- **Low quiescent current in standby mode**  

This regulator is commonly used in **automotive, industrial, and portable electronics** where stable power supply with minimal dropout is required.
