Description and Introduction

Micropower 50 mA Ultra Low-Dropout Regulator in SOT-23 and micro SMD Packages The LP2982IM5-4.0 is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (formerly National Semiconductor, NS).  

### **Specifications:**  
- **Output Voltage:** 4.0V (fixed)  
- **Output Current:** 150mA  
- **Dropout Voltage:** 300mV (typical at full load)  
- **Input Voltage Range:** 2.5V to 16V  
- **Low Quiescent Current:** 75µA (typical)  
- **Low Shutdown Current:** <1µA  
- **Accuracy:** ±2% over line, load, and temperature  
- **Package:** SOT-23-5  
- **Operating Temperature Range:** -40°C to +125°C  

### **Descriptions and Features:**  
- Designed for battery-powered applications requiring stable voltage regulation.  
- Features low dropout voltage, making it suitable for low-input voltage conditions.  
- Includes thermal shutdown and current limit protection.  
- Stable with low-ESR ceramic capacitors (≥1µF).  
- Low noise and high PSRR (Power Supply Rejection Ratio).  
- Available in a small SOT-23-5 package for space-constrained designs.  

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