Description and Introduction

Micropower 100 mA Ultra Low-Dropout Regulator in SOT-23 and micro SMD Packages The LP2981AIM5X-3.3 is a low-dropout (LDO) voltage regulator manufactured by NS国半 (National Semiconductor).  

### **Specifications:**  
- **Output Voltage:** 3.3V (fixed)  
- **Input Voltage Range:** Up to 16V  
- **Dropout Voltage:** 300mV (typical at 150mA load)  
- **Output Current:** 150mA (maximum)  
- **Accuracy:** ±1.5% (over line, load, and temperature)  
- **Quiescent Current:** 75µA (typical)  
- **Package:** SOT-23-5  
- **Operating Temperature Range:** -40°C to +125°C  
- **Protection Features:**  
  - Thermal shutdown  
  - Current limit  

### **Descriptions and Features:**  
- Designed for battery-powered applications requiring stable voltage regulation.  
- Low dropout voltage ensures efficient operation even with small input-output differentials.  
- Stable with low-ESR ceramic capacitors (≥1µF).  
- Low quiescent current extends battery life in portable devices.  
- Suitable for noise-sensitive applications due to low output noise.  

This regulator is commonly used in portable electronics, embedded systems, and power-sensitive applications.
