Description and Introduction

800mA Low-Dropout Linear Regulator The LM1117T-1.8 is a low dropout voltage regulator manufactured by National Semiconductor (NS). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Output Voltage:** 1.8V (fixed)  
- **Output Current:** 800mA (typical)  
- **Dropout Voltage:** 1.2V (max) 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 Type:** TO-220 (through-hole)  

### **Descriptions:**
- The LM1117T-1.8 is a fixed-output, low dropout linear regulator designed to provide a stable 1.8V output.  
- It is suitable for applications requiring efficient voltage regulation with minimal power dissipation.  
- Includes built-in thermal shutdown and current limit protection for enhanced reliability.  

### **Features:**
- **Low Dropout Voltage:** Ensures efficient regulation even when the input voltage is close to the output.  
- **High Accuracy:** Tight output voltage tolerance (±1%).  
- **Thermal Protection:** Prevents damage due to overheating.  
- **Current Limiting:** Protects the regulator and load from excessive current.  
- **Stable with Low-ESR Capacitors:** Works reliably with ceramic or tantalum output capacitors.  

This information is derived from the manufacturer's datasheet and technical documentation.

Description and Introduction

800mA Low-Dropout Linear Regulator The LM1117T-1.8 is a low dropout voltage regulator manufactured by NSC/AP (National Semiconductor/Advanced Power).  

### **Specifications:**  
- **Output Voltage:** 1.8V (fixed)  
- **Output Current:** Up to 800mA  
- **Dropout Voltage:** 1.2V (typical at full load)  
- **Input Voltage Range:** Up to 15V  
- **Line Regulation:** 0.2% (typical)  
- **Load Regulation:** 0.4% (typical)  
- **Operating Temperature Range:** 0°C to +125°C  
- **Package:** TO-220 (through-hole)  

### **Descriptions:**  
The LM1117T-1.8 is a positive voltage regulator designed to provide a stable 1.8V output with low dropout voltage. It is suitable for applications requiring efficient power management, such as in microcontrollers, digital circuits, and portable devices.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient regulation even with small input-output differentials.  
- **Current Limiting & Thermal Protection:** Safeguards against overload and overheating.  
- **High Accuracy:** Tight output voltage tolerance (±1%).  
- **Stable with Low-ESR Capacitors:** Works reliably with ceramic or tantalum capacitors.  
- **Fixed Output Voltage:** Eliminates the need for external resistors.  

This regulator is commonly used in battery-powered systems, embedded applications, and power supply circuits.
