Description and Introduction

1.5A, 500kHz Step-down Voltage Regulator The LM1572MTC-ADJ is a switching regulator manufactured by National Semiconductor (NS). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Input Voltage Range:** 4V to 40V  
- **Output Voltage Range:** Adjustable (1.23V to 37V)  
- **Output Current:** Up to 1.5A  
- **Switching Frequency:** 100kHz (fixed)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TSSOP-16  

### **Descriptions:**
The LM1572MTC-ADJ is a step-down (buck) switching regulator designed for high-efficiency voltage conversion. It features an adjustable output voltage, making it suitable for a wide range of applications. The regulator includes built-in protection features such as thermal shutdown and current limiting.

### **Features:**
- **Adjustable Output Voltage** (via external resistors)  
- **Internal Soft-Start** to reduce inrush current  
- **Thermal Shutdown Protection**  
- **Current Limiting Protection**  
- **Wide Input Voltage Range** (4V to 40V)  
- **Low Dropout Operation**  
- **High Efficiency** (up to 90%)  
- **Fixed Frequency Operation** (100kHz)
