Description and Introduction

800mA Low-Dropout Linear Regulator The LM1117MP-3.3 is a low-dropout linear voltage regulator manufactured by **National Semiconductor (now part of Texas Instruments)**.  

### **Specifications:**  
- **Output Voltage:** 3.3V (fixed)  
- **Output Current:** Up to 800mA  
- **Dropout Voltage:** Typically 1.2V at full load  
- **Input Voltage Range:** Up to 15V  
- **Line Regulation:** 0.2% (typical)  
- **Load Regulation:** 0.4% (typical)  
- **Package:** TO-252 (DPAK)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Protection Features:** Thermal shutdown, current limit  

### **Descriptions & Features:**  
- Designed for **low-dropout (LDO)** applications.  
- Provides stable 3.3V output with high accuracy.  
- Suitable for **battery-powered devices, industrial, and consumer electronics**.  
- Requires only a small output capacitor for stability.  
- **Thermal shutdown** prevents overheating.  
- **Current limiting** protects against short circuits.  

This regulator is commonly used in power supply circuits where a stable 3.3V output is required from a higher input voltage.
