Description and Introduction

Negative Low Dropout Regulator The LM2990S-15 is a low-dropout (LDO) negative voltage regulator manufactured by National Semiconductor (NS).  

### **Specifications:**  
- **Output Voltage:** -15V  
- **Output Current:** 1A  
- **Dropout Voltage:** 0.6V (typical) at full load  
- **Input Voltage Range:** -16V to -26V  
- **Line Regulation:** 0.02% (typical)  
- **Load Regulation:** 0.05% (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-263 (D2PAK)  

### **Descriptions:**  
The LM2990S-15 is a fixed-output negative voltage regulator designed to provide a stable -15V output. It features low dropout voltage, making it suitable for applications with tight input-output differential requirements.  

### **Features:**  
- Fixed -15V output  
- Low dropout voltage  
- Overcurrent and thermal protection  
- Reverse-battery protection  
- Available in a surface-mount TO-263 package  
- High accuracy output voltage  

This regulator is commonly used in power supply applications requiring a stable negative voltage rail.
