Description and Introduction

Micropower, 150mA Ultra Low-Dropout CMOS Voltage Regulator With Power Good The LP3988IMF-3.0 is a low-dropout (LDO) voltage regulator manufactured by National Semiconductor (NSC). Here are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 3.0V (fixed)  
- **Output Current:** 300mA  
- **Dropout Voltage:** 300mV (typical at 300mA load)  
- **Input Voltage Range:** 2.5V to 6.0V  
- **Quiescent Current:** 75µA (typical)  
- **Line Regulation:** 0.05% (typical)  
- **Load Regulation:** 0.1% (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5  

### **Descriptions:**
- The LP3988IMF-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).  
- The device includes thermal shutdown and current limit protection.  

### **Features:**
- **Low Dropout Voltage:** Ensures efficient operation with minimal headroom.  
- **Low Quiescent Current:** Extends battery life in portable applications.  
- **Fast Transient Response:** Suitable for dynamic load conditions.  
- **Thermal Shutdown & Current Limit Protection:** Enhances reliability.  
- **Stable with Low-ESR Ceramic Capacitors:** Reduces external component count.  
- **High PSRR:** Minimizes noise in sensitive applications.  

This information is based on the manufacturer's datasheet.
