- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-263 (D2PAK-5)  
- **Protection Features:**  
  - Thermal shutdown  
  - Current limit  

### **Descriptions and Features:**  
- Designed for **low-power applications** requiring stable voltage regulation.  
- **Low dropout voltage** ensures efficient operation even with small input-output differentials.  
- **Thermal shutdown** prevents damage from overheating.  
- **Current limiting** protects against excessive load conditions.  
- Suitable for **battery-powered devices, automotive systems, and industrial controls**.  
- **Surface-mount package (TO-263)** for compact PCB designs.  

This regulator is commonly used in **portable electronics, embedded systems, and power management circuits**.
