Description and Introduction

Dual Micropower 150 mA Ultra Low-Dropout CMOS Voltage Regulators in micro SMD Package The LP3986BLX-2929 is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments. Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Output Voltage:** 2.925V (fixed)  
- **Output Current:** 300mA  
- **Dropout Voltage:** 200mV (typical) at 300mA  
- **Input Voltage Range:** 2.5V to 6.5V  
- **Line Regulation:** 0.02% (typical)  
- **Load Regulation:** 0.1% (typical)  
- **Quiescent Current:** 75µA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Type:** SOT-23-5  

### **Descriptions:**  
- The LP3986BLX-2929 is a high-performance LDO regulator designed for battery-powered applications.  
- It provides a stable 2.925V output with low noise and high PSRR (Power Supply Rejection Ratio).  
- Features thermal shutdown and current limit protection for reliability.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Low Noise:** Optimized for noise-sensitive applications.  
- **High PSRR:** 75dB at 1kHz, improving performance in noisy environments.  
- **Thermal Shutdown & Current Limit Protection:** Enhances device safety.  
- **Stable with Low-ESR Ceramic Capacitors:** Reduces external component count.  
- **Fast Transient Response:** Suitable for dynamic load conditions.  

This information is based on the manufacturer's datasheet. For detailed electrical characteristics and application notes, refer to the official Texas Instruments documentation.
