Description and Introduction

100 mA, SOT-23, Quasi Low-Dropout Linear Voltage Regulator The LM3480IM3X-5.0 is a step-down switching regulator manufactured by National Semiconductor (now part of Texas Instruments).  

**Specifications:**  
- **Output Voltage:** Fixed 5.0V  
- **Input Voltage Range:** 4.5V to 35V  
- **Output Current:** Up to 100mA  
- **Switching Frequency:** 100kHz (typical)  
- **Efficiency:** Up to 85%  
- **Package:** SOT-23-5 (Thin)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Regulation Type:** Buck (Step-Down)  

**Descriptions:**  
The LM3480IM3X-5.0 is a low-power, step-down DC-DC converter designed for simple and efficient voltage regulation. It integrates a power switch and control circuitry, requiring minimal external components.  

**Features:**  
- Fixed 5.0V output  
- Low quiescent current (50µA typical)  
- Internal soft-start  
- Short-circuit and thermal protection  
- Small footprint (SOT-23-5 package)  
- Suitable for battery-powered and industrial applications  

This regulator is commonly used in applications requiring a stable 5V supply from a higher input voltage.
