Description and Introduction

POSITIVE VOLTAGE REGULATORS The L78L05ACU is a positive voltage regulator manufactured by STMicroelectronics.  

### **Specifications:**  
- **Output Voltage:** 5V  
- **Output Current:** 100mA  
- **Input Voltage Range:** Up to 30V  
- **Dropout Voltage:** 1.7V (typical)  
- **Line Regulation:** 100mV (typical)  
- **Load Regulation:** 15mV (typical)  
- **Operating Temperature Range:** 0°C to +125°C  
- **Package:** TO-92  

### **Descriptions:**  
The L78L05ACU is a fixed 5V linear voltage regulator designed for low-power applications. It provides stable voltage regulation with built-in thermal overload protection and short-circuit protection.  

### **Features:**  
- **Fixed 5V Output**  
- **Thermal Overload Protection**  
- **Short-Circuit Protection**  
- **No External Components Required** (for basic operation)  
- **Low Quiescent Current**  
- **Wide Input Voltage Range**  

This regulator is commonly used in consumer electronics, industrial controls, and other low-power circuits requiring a stable 5V supply.
