Description and Introduction

Micropower, 150mA Low-Noise Ultra Low-Dropout CMOS Voltage Regulator The LP3985IM5-5.0 is a low-dropout (LDO) voltage regulator manufactured by National Semiconductor (NSC). Here are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Output Voltage:** 5.0V (fixed)  
- **Output Current:** 150mA  
- **Input Voltage Range:** 2.5V to 6.5V  
- **Dropout Voltage:** 120mV (typical at 100mA load)  
- **Line Regulation:** 0.02%/V (typical)  
- **Load Regulation:** 0.05%/mA (typical)  
- **Quiescent Current:** 75µA (typical)  
- **Package:** SOT-23-5  
- **Operating Temperature Range:** -40°C to +125°C  

### **Descriptions:**  
- The LP3985IM5-5.0 is a high-performance LDO regulator designed for battery-powered applications.  
- It provides stable 5.0V output with low noise and high PSRR (Power Supply Rejection Ratio).  
- Features thermal shutdown and current limit protection.  

### **Features:**  
- **Ultra-Low Dropout Voltage:** Ensures efficient operation with minimal headroom.  
- **Low Quiescent Current:** Extends battery life in portable devices.  
- **Stable with Low-ESR Capacitors:** Works with ceramic capacitors (≥1µF).  
- **Fast Transient Response:** Suitable for dynamic load conditions.  
- **Thermal Shutdown & Current Limit Protection:** Enhances reliability.
