Description and Introduction

Precision Reference The LM299H is a negative voltage regulator manufactured by National Semiconductor (NS). Below are its specifications, descriptions, and features based on available factual information:

### **Specifications:**  
- **Output Voltage:** -5V to -24V (adjustable)  
- **Output Current:** 1A (maximum)  
- **Input Voltage Range:** -3V to -26V  
- **Dropout Voltage:** 1V (typical)  
- **Line Regulation:** 0.01%/V (typical)  
- **Load Regulation:** 0.3% (typical)  
- **Operating Temperature Range:** 0°C to +125°C  
- **Package:** TO-39 (Metal Can)  

### **Descriptions:**  
- The LM299H is a fixed or adjustable negative voltage regulator designed for high-performance applications.  
- It provides stable output voltage with low dropout, making it suitable for power supply designs.  
- The device includes thermal shutdown and current limiting for protection against overloads.  

### **Features:**  
- **Adjustable or Fixed Output Voltage** (requires external resistors for adjustment).  
- **Thermal Shutdown Protection** to prevent overheating.  
- **Current Limiting** for short-circuit protection.  
- **Low Dropout Voltage** (1V typical).  
- **High Ripple Rejection** for noise-sensitive applications.  
- **Stable Operation with Low ESR Capacitors.**  

This information is based on the manufacturer's datasheet and technical documentation. For detailed electrical characteristics and application notes, refer to the official datasheet.
