Description and Introduction

ADVANCED VOLTAGE REGULATOR The part L4938E is a low-drop voltage regulator manufactured by STMicroelectronics (STM). Here are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Input Voltage Range:** Up to 28V  
- **Output Voltage Options:** 5V (fixed)  
- **Output Current:** Up to 250mA  
- **Dropout Voltage:** Typically 0.4V at 250mA  
- **Line Regulation:** 0.2% (typical)  
- **Load Regulation:** 0.4% (typical)  
- **Quiescent Current:** 1.5mA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-92, DPAK  

### **Descriptions:**  
- The L4938E is a low-dropout (LDO) voltage regulator designed for automotive and industrial applications.  
- It includes built-in protection features such as thermal shutdown, short-circuit protection, and reverse polarity protection.  
- It is optimized for low quiescent current, making it suitable for battery-powered applications.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Thermal Protection:** Prevents damage from overheating.  
- **Short-Circuit Protection:** Safeguards the regulator during fault conditions.  
- **Reverse Polarity Protection:** Enhances reliability in automotive applications.  
- **Low Quiescent Current:** Ideal for power-sensitive designs.  

This information is strictly based on the manufacturer's datasheet and technical documentation.
