Description and Introduction

Adjustable Micropower Low-Dropout Voltage Regulator The LP2953AIN-3.3 is a low-dropout (LDO) voltage regulator manufactured by National Semiconductor (NS).  

### **Specifications:**  
- **Output Voltage:** 3.3V (fixed)  
- **Output Current:** Up to 250mA  
- **Dropout Voltage:** Typically 380mV at full load  
- **Input Voltage Range:** 4V to 30V  
- **Low Quiescent Current:** Typically 75µA  
- **Low Shutdown Current:** <1µA  
- **Accuracy:** ±2% over line, load, and temperature  
- **Package:** 8-pin PDIP (Plastic Dual In-Line Package)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Protection Features:**  
  - Reverse battery protection  
  - Current limit  
  - Thermal shutdown  

### **Descriptions:**  
The LP2953AIN-3.3 is a high-performance LDO regulator designed for applications requiring stable voltage with low power consumption. It is suitable for battery-powered systems, industrial controls, and automotive applications due to its wide input voltage range and robust protection features.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient regulation even when input voltage is close to output.  
- **Low Quiescent Current:** Extends battery life in portable applications.  
- **Thermal Shutdown & Current Limit:** Protects the device from overheating and overcurrent conditions.  
- **Reverse Battery Protection:** Safeguards against incorrect power supply connections.  
- **Stable with Low-ESR Capacitors:** Works reliably with ceramic or tantalum output capacitors.  

This regulator is ideal for systems requiring precise voltage regulation with minimal power loss.
