250kHz Low Supply Current High Efficiency 1.5A Switching Regulator The LT1373CS8#TR is a high efficiency switching regulator manufactured by Linear Technology (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 3V to 30V  
- **Output Voltage Range:** Adjustable from 1.25V to 30V  
- **Output Current:** Up to 3A  
- **Switching Frequency:** 500kHz  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOIC-8  

### **Descriptions:**
- The LT1373CS8#TR is a current-mode switching regulator with high efficiency and low dropout performance.  
- It includes an onboard power switch, oscillator, control circuitry, and protection features.  
- Designed for step-down (buck) applications, it is suitable for battery-powered and industrial systems.  

### **Features:**
- **High Efficiency:** Minimizes power loss with synchronous rectification.  
- **Wide Input Range:** Supports operation from 3V to 30V.  
- **Adjustable Output:** Configurable via external resistors.  
- **Current Mode Control:** Ensures stable operation and fast transient response.  
- **Built-in Protection:** Includes thermal shutdown, current limiting, and undervoltage lockout (UVLO).  
- **Low Dropout Operation:** Maintains regulation even when input voltage is close to output.  

This device is commonly used in power supplies, battery chargers, and DC-DC converters.
