Description and Introduction

5A and 3A Low Dropout Fast Response Regulators The LMS1585 is a low dropout (LDO) voltage regulator manufactured by National Semiconductor (NS). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Output Voltage Range:** Adjustable (1.25V to 5.5V) or fixed (3.3V, 3.45V, 3.6V, 5V).  
- **Output Current:** Up to 3A.  
- **Dropout Voltage:** 1.1V (typical) at full load.  
- **Input Voltage Range:** 4.75V to 7V (for fixed 3.3V output), up to 12V for adjustable version.  
- **Line Regulation:** 0.02% (typical).  
- **Load Regulation:** 0.1% (typical).  
- **Quiescent Current:** 10mA (typical).  
- **Operating Temperature Range:** -40°C to +125°C.  
- **Package Options:** TO-263 (D2PAK), TO-220.  

### **Descriptions:**  
- The LMS1585 is a high-performance LDO regulator designed for applications requiring high current and low dropout voltage.  
- It includes thermal shutdown and current limit protection.  
- Suitable for powering microprocessors, FPGAs, and other high-current loads.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient regulation even with small input-output differentials.  
- **High Accuracy:** Tight output voltage tolerance (±2%).  
- **Thermal Protection:** Prevents damage due to overheating.  
- **Current Limit Protection:** Safeguards against excessive load currents.  
- **Adjustable or Fixed Output:** Provides flexibility in design.  

This information is based on the manufacturer's datasheet for the LMS1585.
