Description and Introduction

Micropower 100 mA Ultra Low-Dropout Regulator in SOT-23 and micro SMD Packages The LP2981AIM5-3.2 is a low-dropout (LDO) voltage regulator manufactured by National Semiconductor (NSC). Below are its specifications, descriptions, and features:  

### **Specifications:**  
- **Output Voltage:** 3.2V (Fixed)  
- **Output Current:** 100mA  
- **Dropout Voltage:** 300mV (Typical at 100mA load)  
- **Input Voltage Range:** 2.5V to 16V  
- **Line Regulation:** 0.02%/V (Typical)  
- **Load Regulation:** 0.1% (Typical)  
- **Quiescent Current:** 75µA (Typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5  

### **Descriptions:**  
- The LP2981AIM5-3.2 is a precision LDO regulator designed for low-power applications.  
- It provides stable 3.2V output with low noise and high PSRR (Power Supply Rejection Ratio).  
- Suitable for battery-powered devices, portable electronics, and noise-sensitive applications.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Low Quiescent Current:** Extends battery life in portable applications.  
- **Thermal Shutdown & Current Limit Protection:** Protects the device from overheating and overcurrent conditions.  
- **Stable with Low-ESR Capacitors:** Works reliably with ceramic capacitors (≥1µF).  
- **High PSRR:** Reduces noise in sensitive circuits.  

This information is based on the manufacturer's datasheet. For detailed performance curves and application notes, refer to the official NSC documentation.
