Description and Introduction

Micropower, Ultra-Low-Dropout, Low-Noise, 300-mA CMOS Regulator 8-VSSOP -40 to 85 The LP3982IMM-2.5/NOPB is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (NS).  

### **Specifications:**  
- **Output Voltage:** 2.5V (fixed)  
- **Output Current:** 150mA  
- **Dropout Voltage:** 150mV (typical) at 100mA load  
- **Input Voltage Range:** 2.5V to 6.5V  
- **Low Quiescent Current:** 75µA (typical)  
- **Low Noise:** 30µVRMS (typical)  
- **PSRR (Power Supply Rejection Ratio):** 70dB at 1kHz  
- **Package:** 8-pin VSSOP (MSOP)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Protection Features:** Overcurrent and thermal shutdown  

### **Descriptions:**  
The LP3982 is a high-performance LDO regulator designed for portable and battery-powered applications. It provides stable voltage with low noise and high PSRR, making it suitable for sensitive analog and RF circuits.  

### **Features:**  
- Ultra-low dropout voltage  
- High PSRR for noise-sensitive applications  
- Stable with low-ESR ceramic capacitors (≥1µF)  
- Thermal shutdown and current limit protection  
- Small footprint (VSSOP-8 package)  

This part is RoHS-compliant and lead-free (NOPB).
