Description and Introduction

Micropower 100 mA Ultra Low-Dropout Regulator in SOT-23 and micro SMD Packages The LP2981AIM5X-5.0 is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (formerly National Semiconductor, NS).  

### **Specifications:**  
- **Output Voltage:** 5.0V (fixed)  
- **Output Current:** 100mA  
- **Dropout Voltage:** 300mV (typical at 100mA load)  
- **Input Voltage Range:** Up to 16V  
- **Low Quiescent Current:** 75µA (typical)  
- **Low Shutdown Current:** 0.01µA (typical)  
- **Accuracy:** ±2% over line, load, and temperature  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5 (Miniature 5-Pin Package)  
- **Protection Features:** Thermal shutdown, current limit  

### **Descriptions:**  
The LP2981AIM5X-5.0 is a high-performance LDO regulator designed for battery-powered applications. It provides a stable 5.0V output with very low dropout voltage, making it suitable for systems where input voltage is close to the output voltage.  

### **Features:**  
- Ultra-low dropout performance  
- Stable with low-ESR ceramic capacitors (≥1µF)  
- Low noise operation  
- Fast transient response  
- Thermal shutdown and current limit protection  
- RoHS-compliant  

This regulator is commonly used in portable electronics, battery-powered devices, and noise-sensitive applications.
