Description and Introduction

VERY LOW DROP VOLTAGE REGULATORS WITH INHIBIT The part L4931 is a low-drop voltage regulator manufactured by STMicroelectronics. Here are the key specifications, descriptions, and features:

### **Specifications:**  
- **Output Voltage:** 5V (fixed)  
- **Output Current:** Up to 250mA  
- **Dropout Voltage:** 0.4V (typical at 100mA load)  
- **Input Voltage Range:** Up to 28V  
- **Low Quiescent Current:** 0.4mA (typical)  
- **Low Standby Current:** < 10μA (when disabled)  
- **Operating Temperature Range:** -40°C to +125°C  

### **Descriptions:**  
- The L4931 is a monolithic integrated voltage regulator designed for automotive and industrial applications.  
- It includes features such as thermal shutdown, short-circuit protection, and reverse polarity protection.  
- Available in multiple package options, including TO-220 and DPAK.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient regulation even with small input-output differentials.  
- **Thermal Protection:** Automatically shuts down in case of excessive temperature.  
- **Short-Circuit Protection:** Safeguards the device against output shorts.  
- **Reverse Polarity Protection:** Withstands reverse battery conditions.  
- **Enable Function:** Allows the regulator to be turned on/off via an external logic signal.  

For detailed electrical characteristics and application notes, refer to the official STMicroelectronics datasheet.
