Description and Introduction

1A LOWDROP OUT VOLTAGE REGULATOR (ADJUSTABLE & FIXED) The LM1117-S is a low dropout voltage regulator manufactured by Fairchild Semiconductor. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Output Voltage Options:** Fixed (1.8V, 2.5V, 3.3V, 5V) or Adjustable (1.25V to 13.8V).  
- **Output Current:** Up to 800mA.  
- **Dropout Voltage:** Typically 1.2V at full load current.  
- **Line Regulation:** 0.2% (typical).  
- **Load Regulation:** 0.4% (typical).  
- **Operating Temperature Range:** -40°C to +125°C.  
- **Package Type:** TO-263 (SMD).  

### **Descriptions:**  
- The LM1117-S is a positive voltage regulator designed to provide a stable output voltage with low dropout.  
- It includes current limiting and thermal shutdown for protection.  
- Suitable for battery-powered applications and other low-voltage systems.  

### **Features:**  
- Low dropout voltage (1.2V typical at full load).  
- Available in fixed and adjustable output versions.  
- Overcurrent and thermal protection.  
- Stable with low-ESR ceramic capacitors (≥10µF).  
- High accuracy (±1% for fixed versions).  

This information is based solely on the manufacturer's datasheet.
