Description and Introduction

800mA Low-Dropout Linear Regulator The LM1117DT-2.85 is a low dropout voltage regulator manufactured by NS (National Semiconductor). Here are its specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 2.85V (fixed)  
- **Output Current:** 800mA  
- **Dropout Voltage:** 1.2V (typical at 800mA load)  
- **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-2.85 is a positive voltage regulator designed to provide a stable 2.85V output with high efficiency and low dropout voltage. It is suitable for applications requiring precise voltage regulation, such as in portable devices, microcontrollers, and power supplies.

### **Features:**
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Current Limiting & Thermal Protection:** Protects the device from overload and overheating.  
- **Stable with Low-ESR Capacitors:** Works reliably with ceramic or tantalum output capacitors.  
- **High Accuracy:** Tight output voltage tolerance (±1%).  
- **SMD Package:** TO-252 (DPAK) for surface-mount applications.  

This regulator is widely used in battery-powered systems and embedded applications where stable voltage regulation is critical.
