Description and Introduction

Micropower 50 mA Ultra Low-Dropout Regulator In SOT-23 and micro SMD Packages The LP2980IM5X-3.8 is a low-dropout (LDO) voltage regulator manufactured by National Semiconductor (NS). Below are its specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 3.8V (fixed)  
- **Output Current:** 50mA  
- **Dropout Voltage:** 80mV (typical at 10mA load)  
- **Input Voltage Range:** Up to 16V  
- **Line Regulation:** 0.02%/V (typical)  
- **Load Regulation:** 0.2% (typical)  
- **Quiescent Current:** 75µA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5  

### **Descriptions:**
- The LP2980IM5X-3.8 is a precision, low-power LDO regulator designed for battery-powered applications.  
- It provides a stable 3.8V output with low dropout voltage, making it suitable for systems with tight voltage margins.  
- Features low quiescent current, enhancing efficiency in portable devices.  

### **Features:**  
- **Low Dropout Voltage:** Ensures stable operation even with small input-output differentials.  
- **Low Quiescent Current:** Optimized for battery-powered applications.  
- **Thermal Shutdown & Current Limit Protection:** Protects the device from overheating and overcurrent conditions.  
- **Stable with Low-ESR Capacitors:** Works with ceramic capacitors (≥1µF).  
- **High PSRR (Power Supply Rejection Ratio):** Reduces noise in sensitive applications.  

This regulator is commonly used in portable electronics, medical devices, and precision analog circuits.
