Description and Introduction

Extended Temperature Adjustable Linear Regulator with Short Circuit Protection 3-TO -55 to 150 The LM117H/NOPB is a high-performance voltage regulator manufactured by National Semiconductor (NSC). Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Output Voltage Range:** 1.2V to 37V  
- **Output Current:** 1.5A  
- **Input-Output Voltage Differential (Dropout Voltage):** 3V (max) at full load  
- **Line Regulation:** 0.01%/V (typ)  
- **Load Regulation:** 0.1% (typ)  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package Type:** TO-39 (Metal Can)  
- **Reference Voltage:** 1.25V  
- **Thermal Resistance (Junction-to-Case):** 23°C/W  

### **Descriptions:**  
- The LM117H/NOPB is a three-terminal adjustable positive voltage regulator designed to supply up to 1.5A of load current.  
- It requires only two external resistors to set the output voltage.  
- The device features internal current limiting, thermal shutdown, and safe operating area protection.  
- It is suitable for a wide range of applications, including power supplies, industrial controls, and instrumentation.  

### **Features:**  
- **Adjustable Output Voltage:** Easily set with two external resistors.  
- **High Efficiency:** Low dropout voltage improves efficiency.  
- **Thermal Overload Protection:** Prevents damage due to excessive heat.  
- **Short-Circuit Protection:** Safeguards against output short circuits.  
- **Stable Operation:** Works reliably with low-ESR capacitors.  
- **Wide Operating Temperature Range:** Suitable for harsh environments.  

This information is based solely on the manufacturer's datasheet for the LM117H/NOPB.
