Description and Introduction

DUAL MULTIFUNCTION VOLTAGE REGULATOR The part **L4938ND013TR** is a voltage regulator manufactured by **STMicroelectronics (ST)**. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:**  
STMicroelectronics (ST)  

### **Description:**  
The **L4938ND013TR** is a low-dropout (LDO) voltage regulator designed for automotive and industrial applications. It provides a fixed output voltage with high accuracy and low quiescent current.  

### **Key Features:**  
- **Output Voltage:** Fixed (specific value depends on variant, e.g., 1.8V, 3.3V, 5V, etc.)  
- **Output Current:** Up to 250 mA  
- **Low Dropout Voltage:** Typically 0.4V at full load  
- **Input Voltage Range:** Up to 28V (with transient protection up to 40V)  
- **Low Quiescent Current:** Typically 50 µA in standby mode  
- **Thermal Shutdown Protection:** Prevents overheating  
- **Short-Circuit Protection:** Ensures device safety  
- **Reverse Polarity Protection:** Safeguards against incorrect connections  
- **AEC-Q100 Qualified:** Suitable for automotive applications  
- **Package:** SO-8 (Surface Mount)  

### **Applications:**  
- Automotive electronics (ECUs, sensors, infotainment)  
- Industrial control systems  
- Battery-powered devices
