Description and Introduction

Negative Low Dropout Regulator 3-DDPAK/TO-263 -40 to 125 The LM2990S-5.0/NOPB is a low-dropout (LDO) voltage regulator manufactured by National Semiconductor (NS). Below are its specifications, descriptions, and features:  

### **Specifications:**  
- **Output Voltage:** 5.0V (fixed)  
- **Output Current:** 1A  
- **Dropout Voltage:** 0.6V (typical at full load)  
- **Input Voltage Range:** Up to 26V  
- **Line Regulation:** 0.3% (typical)  
- **Load Regulation:** 0.5% (typical)  
- **Quiescent Current:** 10mA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-263 (D2PAK)  

### **Descriptions:**  
- The LM2990S-5.0/NOPB is a negative-voltage regulator designed for applications requiring a stable -5V supply.  
- It features thermal shutdown and current limit protection for enhanced reliability.  
- Suitable for powering analog and digital circuits in automotive, industrial, and consumer applications.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient regulation even with small input-output differentials.  
- **Thermal Shutdown Protection:** Prevents damage due to excessive heat.  
- **Current Limit Protection:** Safeguards against short circuits and overloads.  
- **Wide Input Voltage Range:** Supports up to 26V input.  
- **Stable with Low-ESR Capacitors:** Reduces external component requirements.
