- **Package Options:** TO-92, SOT-223, SOIC-8  

### **Descriptions:**  
The LM2931-5.0 is a positive voltage regulator designed to maintain a stable 5.0V output with very low dropout voltage, making it suitable for battery-powered applications. It includes features such as reverse battery protection, thermal shutdown, and current limiting for enhanced reliability.  

### **Features:**  
- Low dropout voltage (0.6V typical at 100mA)  
- Reverse battery protection  
- Internal thermal shutdown  
- Short-circuit and current-limit protection  
- Low quiescent current  
- Stable with low-ESR capacitors  
- Wide operating temperature range (-40°C to +125°C)  

This regulator is commonly used in automotive, industrial, and portable electronics applications.
