### **Specifications:**
- **Output Voltage:** 1.5V  
- **Output Current:** Up to 1A  
- **Dropout Voltage:** Typically 0.5V at full load  
- **Input Voltage Range:** Up to 26V  
- **Line Regulation:** 0.3% (Typical)  
- **Load Regulation:** 0.4% (Typical)  
- **Quiescent Current:** 10mA (Typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Type:** TO-263 (SMD)  

### **Descriptions:**
- The LM2940CSX-1.5 is a fixed-output LDO regulator designed to provide a stable 1.5V supply.  
- It includes built-in protection features such as thermal shutdown and current limiting.  
- Suitable for battery-powered applications due to its low dropout voltage.  

### **Features:**
- Low dropout voltage (0.5V typical at 1A)  
- Thermal shutdown protection  
- Short-circuit current limiting  
- Reverse battery protection  
- Low quiescent current  
- Stable with low-ESR capacitors  

This regulator is commonly used in automotive, industrial, and consumer electronics applications requiring a reliable 1.5V power supply.
