Description and Introduction

Micropower 100 mA Ultra Low-Dropout Regulator in SOT-23 and micro SMD Packages The LP2981IM5X-3.2 is a low-dropout (LDO) voltage regulator manufactured by National Semiconductor (NS).  

### **Specifications:**  
- **Output Voltage:** 3.2V (fixed)  
- **Output Current:** 100mA  
- **Dropout Voltage:** 300mV (typical) at 100mA load  
- **Input Voltage Range:** 2.3V to 16V  
- **Low Quiescent Current:** 75µA (typical)  
- **Low Shutdown Current:** 0.01µA (typical)  
- **Accuracy:** ±1.5% over line, load, and temperature  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5  

### **Descriptions & Features:**  
- Designed for battery-powered applications requiring low quiescent current.  
- Stable with low-ESR ceramic capacitors (≥1µF).  
- Includes thermal shutdown and current limit protection.  
- Low noise and high PSRR (Power Supply Rejection Ratio).  
- Suitable for portable electronics, wireless devices, and power-sensitive applications.  

This regulator ensures stable voltage output with minimal power loss, making it ideal for space-constrained and energy-efficient designs.
