Description and Introduction

Dual Micropower 150 mA Ultra Low-Dropout CMOS Voltage Regulators in micro SMD Package The LP3986TL-3333 is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Output Voltage:** 3.333V (fixed)  
- **Output Current:** 300mA  
- **Dropout Voltage:** 150mV (typical at 300mA load)  
- **Input Voltage Range:** 2.5V to 6.5V  
- **Line Regulation:** 0.02%/V (typical)  
- **Load Regulation:** 0.05%/mA (typical)  
- **Quiescent Current:** 75µA (typical)  
- **PSRR (Power Supply Rejection Ratio):** 75dB at 1kHz  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5  

### **Descriptions:**  
- The LP3986TL-3333 is a high-performance, low-noise LDO regulator designed for battery-powered applications.  
- It provides a stable 3.333V output with high accuracy (±1.5%).  
- Features ultra-low dropout voltage, making it suitable for low-input voltage conditions.  
- Includes built-in protection features such as thermal shutdown and current limit.  

### **Features:**  
- **Low Dropout Voltage:** 150mV typical at 300mA load.  
- **Low Noise:** Optimized for noise-sensitive applications.  
- **Fast Transient Response:** Ensures stable output under varying load conditions.  
- **Thermal Shutdown & Current Limit Protection:** Safeguards the device from overheating and overcurrent.  
- **Stable with Low-ESR Ceramic Capacitors:** Reduces external component count.  
- **Small Form Factor:** SOT-23-5 package for space-constrained designs.  

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