Description and Introduction

Micropower 50 mA Ultra Low-Dropout Regulator In SOT-23 and micro SMD Packages The LP2980IM5-4.0 is a low-dropout (LDO) voltage regulator manufactured by National Semiconductor (now part of Texas Instruments).  

### **Specifications:**  
- **Output Voltage:** 4.0V (fixed)  
- **Output Current:** 50mA  
- **Dropout Voltage:** 80mV (typical at 10mA load)  
- **Input Voltage Range:** Up to 16V  
- **Quiescent Current:** 75µA (typical)  
- **Package Type:** SOT-23-5  
- **Operating Temperature Range:** -40°C to +125°C  
- **Line Regulation:** 0.02%/V (typical)  
- **Load Regulation:** 0.1% (typical)  
- **Protection Features:** Thermal shutdown, current limit  

### **Descriptions and Features:**  
- **Low Dropout:** Operates with very low input-to-output voltage differential.  
- **Low Quiescent Current:** Ideal for battery-powered applications.  
- **Stable with Low-ESR Capacitors:** Works with ceramic capacitors (≥1µF).  
- **High Accuracy:** ±2% output voltage tolerance.  
- **Low Noise:** Suitable for noise-sensitive applications.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Current Limit Protection:** Safeguards against excessive load currents.  

This regulator is commonly used in portable electronics, battery-powered devices, and precision analog circuits.
