Description and Introduction

Micropower, 150mA Low-Noise Ultra Low-Dropout CMOS Voltage Regulator The LP3985ITL-3.0 is a low-dropout (LDO) voltage regulator manufactured by National Semiconductor (NS). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Output Voltage:** 3.0V (fixed)  
- **Output Current:** 150mA  
- **Dropout Voltage:** 120mV (typical) at 150mA load  
- **Input Voltage Range:** 2.5V to 6.0V  
- **Quiescent Current:** 75µA (typical)  
- **Line Regulation:** 0.02%/V (typical)  
- **Load Regulation:** 0.1%/mA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5  

### **Descriptions:**  
- The LP3985ITL-3.0 is a high-performance LDO regulator designed for battery-powered applications.  
- It provides stable voltage regulation with low noise and high PSRR (Power Supply Rejection Ratio).  
- Includes built-in protection features such as thermal shutdown and current limiting.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation with minimal power loss.  
- **Low Quiescent Current:** Ideal for portable and battery-operated devices.  
- **Fast Transient Response:** Maintains stable output under dynamic load conditions.  
- **Thermal Shutdown Protection:** Prevents damage from excessive heat.  
- **Current Limit Protection:** Safeguards against overcurrent conditions.  
- **Stable with Low-ESR Capacitors:** Works with ceramic capacitors (≥1µF).  

This information is based on the manufacturer's datasheet for the LP3985ITL-3.0.
