Description and Introduction

N-Channel FET Synchronous Buck Regulator Controller for Low Output Voltages The LM78L is a positive voltage regulator manufactured by National Semiconductor (NS). Here are its specifications, descriptions, and features:  

### **Specifications:**  
- **Output Voltage Options:** 5V, 6.2V, 8.2V, 9V, 10V, 12V, 15V  
- **Output Current:** 100mA  
- **Input Voltage Range:** Up to 30V (depending on model)  
- **Dropout Voltage:** ~2V  
- **Line Regulation:** 0.1% (typical)  
- **Load Regulation:** 0.3% (typical)  
- **Operating Temperature Range:** 0°C to +125°C  
- **Package Types:** TO-92, SOT-89  

### **Descriptions:**  
- The LM78L is a fixed-output, three-terminal linear voltage regulator.  
- Designed for low-power applications requiring stable voltage regulation.  
- Includes built-in thermal overload protection and short-circuit current limiting.  

### **Features:**  
- **Fixed Output Voltage:** No external components needed for regulation.  
- **Thermal Overload Protection:** Shuts down if temperature exceeds safe limits.  
- **Short-Circuit Protection:** Limits current in case of a fault.  
- **Low Quiescent Current:** Efficient for battery-powered applications.  
- **Wide Input Voltage Range:** Suitable for various power supply designs.  

The LM78L is commonly used in consumer electronics, instrumentation, and low-power circuits.
