Description and Introduction

1A LOWDROP OUT VOLTAGE REGULATOR (ADJUSTABLE & FIXED) The LM1117T is a low dropout voltage regulator manufactured by National Semiconductor (NationalSemi). Below are its specifications, descriptions, and features based on factual information 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:** 0°C to +125°C.  
- **Package Type:** TO-220 (LM1117T).  

### **Descriptions:**  
- The LM1117T is a positive voltage regulator designed to provide a stable output voltage with low dropout.  
- It includes current limiting and thermal shutdown protection.  
- Suitable for battery-powered applications and other systems requiring efficient regulation.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Current Limiting:** Protects the regulator and load from excessive current.  
- **Available in Fixed and Adjustable Versions:** Offers flexibility for different voltage requirements.  
- **Stable with Low-ESR Capacitors:** Works reliably with ceramic or tantalum output capacitors.  

This information is strictly based on the manufacturer's datasheet for the LM1117T by National Semiconductor.
