Description and Introduction

Series of Adjustable Micropower Voltage Regulators The LP2951CN-3.3 is a low-dropout voltage regulator manufactured by National Semiconductor (NS). Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Output Voltage:** 3.3V (fixed)  
- **Output Current:** 100mA  
- **Dropout Voltage:** 380mV (typical at full load)  
- **Input Voltage Range:** Up to 30V  
- **Line Regulation:** 0.03% (typical)  
- **Load Regulation:** 0.3% (typical)  
- **Quiescent Current:** 75µA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Pin DIP (PDIP)  

### **Descriptions:**  
- The LP2951CN-3.3 is a precision voltage regulator with low dropout voltage, designed for battery-powered applications.  
- It includes features such as current limit, thermal shutdown, and reverse battery protection.  
- The device is stable with low-ESR capacitors and provides a stable 3.3V output.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Low Quiescent Current:** Ideal for battery-operated devices.  
- **Thermal Shutdown & Current Limit Protection:** Enhances reliability under fault conditions.  
- **Reverse Battery Protection:** Safeguards against incorrect polarity connection.  
- **Stable with Low-ESR Capacitors:** Reduces external component requirements.  
- **Fixed 3.3V Output:** Eliminates the need for external resistors.  

This information is based on the manufacturer's datasheet for the LP2951CN-3.3 by National Semiconductor.
