Description and Introduction

5V Micropower Low-Dropout Voltage Regulator The LP2954IT is a low-dropout voltage regulator manufactured by National Semiconductor (NSC). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Output Voltage Options:** Fixed (3.3V, 5V) or Adjustable (1.24V to 29V)  
- **Output Current:** Up to 250mA  
- **Dropout Voltage:** Typically 380mV at full load (250mA)  
- **Input Voltage Range:** Up to 30V  
- **Line Regulation:** 0.02% (Typical)  
- **Load Regulation:** 0.04% (Typical)  
- **Quiescent Current:** 75µA (Typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-220  

### **Descriptions:**  
- The LP2954IT is a low-power LDO (Low Dropout) voltage regulator designed for battery-powered applications.  
- It includes features like thermal shutdown, current limit protection, and reverse battery protection.  
- Suitable for automotive, industrial, and portable electronics due to its wide input voltage range.  

### **Features:**  
- **Low Dropout Voltage:** Ensures stable output even with small input-output differentials.  
- **Low Quiescent Current:** Extends battery life in portable applications.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Current Limit Protection:** Safeguards against excessive output current.  
- **Reverse Battery Protection:** Protects the regulator if the input polarity is reversed.  
- **Adjustable Output (for adjustable version):** Allows flexibility in setting the desired output voltage.  

This information is strictly factual from the manufacturer's datasheet.
