Description and Introduction

Micropower, Ultra Low-Dropout, Low-Noise, 300mA CMOS Regulator The LP3982IMMX-3.0 is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (formerly National Semiconductor, NS).  

### **Specifications:**  
- **Output Voltage:** 3.0V (fixed)  
- **Output Current:** 300mA  
- **Dropout Voltage:** 120mV (typical) at 150mA load  
- **Input Voltage Range:** 2.5V to 6.5V  
- **Quiescent Current:** 75µA (typical)  
- **Low Noise:** 30µVRMS (typical)  
- **PSRR:** 75dB at 1kHz  
- **Package:** 8-pin VSSOP (MSOP)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Protection Features:** Overcurrent and thermal shutdown  

### **Descriptions and Features:**  
- Ultra-low dropout voltage for extended battery life in portable applications.  
- Stable with low-ESR ceramic capacitors (≥1µF).  
- High power supply ripple rejection (PSRR) for noise-sensitive applications.  
- Low quiescent current improves efficiency in battery-powered devices.  
- Fast transient response for dynamic load conditions.  
- Thermal shutdown and current limit protection for reliability.  

This regulator is commonly used in portable electronics, wireless devices, and power-sensitive applications.
