Description and Introduction

Micropower, Ultra Low-Dropout, Low-Noise, 300mA CMOS Regulator The LP3982ILDX-3.3 is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (formerly National Semiconductor, NS).  

### **Specifications:**  
- **Output Voltage:** 3.3V (fixed)  
- **Output Current:** 300mA  
- **Dropout Voltage:** 200mV (typical at 300mA load)  
- **Input Voltage Range:** 2.5V to 6.5V  
- **Quiescent Current:** 75µA (typical)  
- **Package:** 6-pin WSON (2mm x 2mm)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Accuracy:** ±2% over line, load, and temperature  
- **Protection Features:** Overcurrent and thermal shutdown  

### **Descriptions and Features:**  
- Ultra-low dropout voltage for extended battery life.  
- Stable with low-ESR ceramic capacitors (≥1µF).  
- Low noise and high PSRR (Power Supply Rejection Ratio).  
- Fast transient response for portable applications.  
- Designed for space-constrained applications due to its small package size.  
- Suitable for battery-powered devices, portable electronics, and wireless applications.  

This regulator is optimized for efficiency and reliability in compact designs.
