Description and Introduction

1.5A STEP DOWN SWITCHING REGULATOR The **L4971D013TR** is a switching regulator IC manufactured by **STMicroelectronics (ST)**. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:**  
STMicroelectronics (ST)  

### **Specifications:**  
- **Type:** Step-Down (Buck) Switching Regulator  
- **Output Voltage:** Adjustable (typically 3.3V, 5V, or other fixed/adj. versions)  
- **Output Current:** Up to 1.5A  
- **Input Voltage Range:** 8V to 55V  
- **Switching Frequency:** 200 kHz (fixed)  
- **Efficiency:** Up to 90%  
- **Package:** SO-8 (Surface Mount)  
- **Protection Features:**  
  - Overcurrent Protection  
  - Thermal Shutdown  
  - Undervoltage Lockout (UVLO)  

### **Descriptions:**  
The L4971D013TR is a monolithic step-down switching regulator designed for high-efficiency DC-DC conversion. It integrates a power MOSFET and control circuitry, making it suitable for applications requiring a stable and adjustable output voltage from a higher input voltage source.  

### **Features:**  
- **Wide Input Voltage Range (8V to 55V)**  
- **High Output Current Capability (1.5A)**  
- **Internal Power MOSFET**  
- **Fixed Switching Frequency (200 kHz)**  
- **Low Dropout Operation**  
- **Soft-Start Function**  
- **Thermal Protection**  
- **Adjustable Output Voltage (with external resistors)**  

This information is based on the manufacturer's datasheet and technical documentation. For detailed electrical characteristics and application circuits, refer to the official STMicroelectronics datasheet.
