Description and Introduction

3-Terminal 0.1A Positive Adjustable Regulator The LM317-LZ is a three-terminal adjustable positive voltage regulator manufactured by STMicroelectronics, Fairchild Semiconductor (FSC), and National Semiconductor (NSC).  

### **Specifications:**  
- **Output Voltage Range:** 1.25V to 37V  
- **Output Current:** 100mA (guaranteed)  
- **Line Regulation:** 0.01%/V (typical)  
- **Load Regulation:** 0.1% (typical)  
- **Operating Junction Temperature:** 0°C to +125°C  
- **Package:** TO-92 (through-hole)  
- **Input-Output Differential Voltage (Dropout):** 3V (typical)  
- **Reference Voltage:** 1.25V (between output and adjust terminal)  

### **Descriptions:**  
- The LM317-LZ is a linear voltage regulator designed to provide a stable, adjustable output voltage with only two external resistors.  
- It includes internal current limiting, thermal shutdown, and safe operating area protection.  
- Suitable for a wide range of applications, including power supplies, battery chargers, and voltage references.  

### **Features:**  
- Adjustable output voltage  
- 100mA guaranteed output current  
- Internal thermal overload protection  
- Short-circuit protection  
- No external components required for fixed voltage operation (except resistors)  
- Low standby current (typically 5mA)  

This information is based on the manufacturer's datasheets from STMicroelectronics, Fairchild Semiconductor, and National Semiconductor.
