Description and Introduction

Micropower 800mA Low Noise Ceramic Stable Voltage Regulator for Low Voltage Applications The part **LP3879MR-1.0** is a low-dropout (LDO) voltage regulator manufactured by **NS (National Semiconductor)**.  

### **Specifications:**  
- **Output Voltage:** 1.0V (fixed)  
- **Output Current:** 800mA  
- **Dropout Voltage:** 340mV (typical at 800mA load)  
- **Input Voltage Range:** 2.5V to 7V  
- **Line Regulation:** 0.02% (typical)  
- **Load Regulation:** 0.05% (typical)  
- **Quiescent Current:** 1.6mA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Pin SOIC (MR)  

### **Descriptions and Features:**  
- **Low Dropout Voltage:** Ensures efficient regulation even with small input-output differentials.  
- **High Accuracy:** Tight output voltage tolerance (±2%).  
- **Low Noise:** Suitable for noise-sensitive applications.  
- **Thermal Shutdown & Current Limit Protection:** Protects the regulator from overheating and overcurrent conditions.  
- **Stable with Low-ESR Capacitors:** Works with ceramic or tantalum output capacitors.  
- **Fast Transient Response:** Maintains stable output under varying load conditions.  

This regulator is commonly used in **battery-powered devices, portable electronics, and embedded systems** requiring a stable 1.0V supply.
