- **Dropout Voltage:** Typically **0.4V** at full load (1.5A)  
- **Input Voltage Range:** Up to **28V**  
- **Line Regulation:** 10mV (typical)  
- **Load Regulation:** 15mV (typical)  
- **Quiescent Current:** 10mA (typical)  
- **Operating Temperature Range:** **-40°C to +125°C**  
- **Package:** **TO-252 (DPAK)**  
- **Protection Features:**  
  - Thermal shutdown  
  - Short-circuit protection  
  - Reverse polarity protection  

### **Description:**  
The **L4940D2T12-TR** is a **fixed-output** LDO regulator designed for high-performance applications requiring stable voltage regulation. It is suitable for automotive, industrial, and consumer electronics due to its robust protection features and wide operating temperature range.  

### **Features:**  
- **Low dropout voltage** (0.4V typical at 1.5A)  
- **High output current capability** (1.5A)  
- **Thermal shutdown protection**  
- **Short-circuit and reverse polarity protection**  
- **Wide input voltage range** (up to 28V)  
- **Stable with low-ESR capacitors**  
- **TO-252 (DPAK) package** for efficient heat dissipation  

This regulator is commonly used in power supply circuits where precise voltage regulation and high reliability are required.
