Description and Introduction

Micropower, Ultra Low-Dropout, Low-Noise, 300mA CMOS Regulator The LP3982IMMX-2.77 is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (NS).  

### **Specifications:**  
- **Output Voltage:** 2.77V (fixed)  
- **Output Current:** 300mA  
- **Dropout Voltage:** 120mV (typical) at 100mA load  
- **Input Voltage Range:** 2.5V to 6.5V  
- **Quiescent Current:** 75µA (typical)  
- **Package:** 8-pin VSSOP (MSOP)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Accuracy:** ±2% over line, load, and temperature variations  
- **PSRR (Power Supply Rejection Ratio):** 60dB at 1kHz  
- **Enable Control:** Yes (active high)  
- **Protection Features:** Overcurrent and thermal shutdown  

### **Descriptions and Features:**  
- Ultra-low dropout voltage for efficient power management.  
- Stable with low-ESR ceramic capacitors (≥1µF).  
- Low quiescent current for battery-powered applications.  
- Fast transient response for dynamic loads.  
- Enable pin allows for power-saving modes.  
- Suitable for portable and noise-sensitive applications.  

This LDO is designed for applications requiring precise voltage regulation with minimal power loss.
