Description and Introduction

100 mA, SOT-23, Quasi Low-Dropout Linear Voltage Regulator The LM3480IM3X-15 is a step-down (buck) switching voltage regulator manufactured by Texas Instruments (NS). Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Output Voltage:** Fixed 1.5V  
- **Input Voltage Range:** 4.5V to 35V  
- **Output Current:** Up to 100mA  
- **Switching Frequency:** 100kHz (typical)  
- **Efficiency:** Up to 80%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5 (Thin)  

### **Descriptions:**  
- The LM3480IM3X-15 is a monolithic buck regulator designed for simple, efficient step-down voltage conversion.  
- It integrates a power switch, oscillator, control circuitry, and protection features in a compact package.  
- Suitable for low-power applications requiring a regulated 1.5V output from higher input voltages.  

### **Features:**  
- **Fixed Output Voltage:** 1.5V with ±4% accuracy.  
- **Low Quiescent Current:** 100µA (typical).  
- **Internal Current Limiting:** Protects against overloads.  
- **Thermal Shutdown:** Prevents damage from excessive heat.  
- **Small Footprint:** SOT-23-5 package for space-constrained designs.  
- **Wide Input Range:** Supports 4.5V to 35V input.  

This regulator is commonly used in battery-powered systems, industrial controls, and embedded applications.
