- **Package Type:** TO-220 (5-pin)  
- **Regulator Type:** Buck (Step-Down)  

### **Descriptions:**
- The LM2575HVT-15 is a monolithic integrated circuit designed for step-down (buck) switching regulator applications.  
- It simplifies power supply design by requiring minimal external components.  
- The device includes a fixed-frequency oscillator, feedback control, and an internal switch.  

### **Features:**
- **Fixed Output Voltage (-15V)**  
- **Wide Input Voltage Range (4.75V to 40V)**  
- **1A Output Current Capability**  
- **Low Power Standby Mode (50 µA typical)**  
- **Internal Frequency Compensation**  
- **Thermal Shutdown and Current Limit Protection**  
- **Requires Only 4 External Components**  
- **Available in TO-220 Package**
