Description and Introduction

150mA Linear Voltage Regulator for Digital Applications The part **LP3990SD-0.8** is manufactured by **NS (National Semiconductor)**. Below are its specifications, descriptions, and features:  

### **Specifications:**  
- **Output Voltage:** 0.8V  
- **Output Current:** 1A  
- **Input Voltage Range:** 2.5V to 6.5V  
- **Dropout Voltage:** 300mV (typical) at 1A  
- **Accuracy:** ±1.5%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 5-Pin SOT-223  

### **Descriptions:**  
- The LP3990SD-0.8 is a low-dropout (LDO) voltage regulator designed for high-performance applications.  
- It provides a fixed 0.8V output with high accuracy and low noise.  
- Suitable for powering low-voltage processors, FPGAs, and other sensitive loads.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **High PSRR (Power Supply Rejection Ratio):** Reduces noise from input supply variations.  
- **Thermal Shutdown & Current Limit Protection:** Enhances reliability under fault conditions.  
- **Stable with Low-ESR Ceramic Capacitors:** Simplifies PCB design.  
- **Low Quiescent Current:** Improves power efficiency in battery-operated systems.  

This information is based solely on the manufacturer's datasheet for the LP3990SD-0.8.
