Description and Introduction

Adjustable Micropower Low-Dropout Voltage Regulator The LP2952IN-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:** 250mA  
- **Dropout Voltage:** 380mV (typical at full load)  
- **Input Voltage Range:** Up to 30V  
- **Line Regulation:** 0.03% (typical)  
- **Load Regulation:** 0.05% (typical)  
- **Quiescent Current:** 75µA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Pin DIP (PDIP)  

### **Descriptions:**  
- The LP2952IN-3.3 is a precision voltage regulator with low dropout, designed for battery-powered applications.  
- It includes features such as error flag warning for low voltage, thermal shutdown, and current limiting.  
- Suitable for industrial, automotive, and portable electronics due to its wide input range and robust protection features.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Low Quiescent Current:** Extends battery life in portable applications.  
- **Error Flag Output:** Warns of impending regulator dropout (output falls out of regulation).  
- **Thermal Shutdown & Current Limit Protection:** Prevents damage from overheating and short circuits.  
- **Stable with Low-ESR Capacitors:** Works reliably with ceramic or tantalum output capacitors.  

This information is based solely on the manufacturer's datasheet for the LP2952IN-3.3.
