Description and Introduction

800mA Low-Dropout Linear Regulator The LM1117DT-3.3 is a low dropout voltage regulator manufactured by ON Semiconductor (NS). Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Output Voltage:** 3.3V (Fixed)  
- **Output Current:** 800mA (Maximum)  
- **Dropout Voltage:** 1.2V (Typical at 800mA)  
- **Input Voltage Range:** Up to 15V  
- **Line Regulation:** 0.2% (Typical)  
- **Load Regulation:** 0.4% (Typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-252 (DPAK)  

### **Descriptions:**  
- The LM1117DT-3.3 is a positive voltage regulator designed to provide a stable 3.3V output with low dropout voltage.  
- It includes current limiting and thermal shutdown protection for enhanced reliability.  
- Suitable for battery-powered and low-voltage applications.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient regulation even with small input-output differentials.  
- **Thermal Overload Protection:** Prevents damage due to excessive heat.  
- **Short-Circuit Protection:** Safeguards the regulator during fault conditions.  
- **Stable with Low-ESR Capacitors:** Works reliably with ceramic or tantalum output capacitors.  
- **High Accuracy:** Tight output voltage tolerance (±1%).  

This information is based solely on the manufacturer's datasheet for the LM1117DT-3.3 from ON Semiconductor.
