Description and Introduction

ADVANCED VOLTAGE REGULATOR The part **L4938EPD** is manufactured by **STMicroelectronics (ST)**. Below are the specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Type:** Low-drop voltage regulator  
- **Output Voltage:** 5V (fixed)  
- **Output Current:** Up to 250mA  
- **Dropout Voltage:** Typically 0.4V at full load  
- **Input Voltage Range:** Up to 28V  
- **Quiescent Current:** Typically 1.5mA  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** PENTAWATT (TO-220 compatible)  

### **Descriptions:**  
- The **L4938EPD** is a low-dropout (LDO) voltage regulator designed for automotive and industrial applications.  
- It provides stable 5V output with high accuracy and low power dissipation.  
- Features built-in protection circuits including thermal shutdown, short-circuit protection, and reverse polarity protection.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient regulation even with small input-output differentials.  
- **Thermal Protection:** Prevents damage due to overheating.  
- **Short-Circuit Protection:** Safeguards the regulator and load.  
- **Reverse Polarity Protection:** Enhances reliability in automotive environments.  
- **Wide Input Voltage Range:** Suitable for harsh electrical conditions.  
- **Low Quiescent Current:** Reduces power consumption in standby mode.  

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