Description and Introduction

3A 550 kHz Synchronous SIMPLE SWITCHER Buck Regulator The LM2853MH-2.5 is a voltage regulator manufactured by National Semiconductor (NS). Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Output Voltage:** 2.5V (fixed)  
- **Output Current:** Up to 500mA  
- **Input Voltage Range:** 4V to 30V  
- **Dropout Voltage:** 300mV (typical)  
- **Line Regulation:** 0.02%/V (typical)  
- **Load Regulation:** 0.1% (typical)  
- **Quiescent Current:** 1.5mA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-263 (D2PAK)  

### **Descriptions:**  
- The LM2853MH-2.5 is a low-dropout (LDO) linear voltage regulator.  
- It provides a fixed 2.5V output with high accuracy and stability.  
- Designed for applications requiring a regulated power supply with low noise and ripple.  
- Includes thermal shutdown and current limit protection.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Thermal Shutdown Protection:** Prevents damage from excessive heat.  
- **Current Limit Protection:** Safeguards against overcurrent conditions.  
- **Wide Input Voltage Range:** Suitable for various power supply configurations.  
- **Stable with Low-ESR Capacitors:** Reduces external component requirements.  
- **High PSRR (Power Supply Rejection Ratio):** Minimizes noise from input voltage variations.  

This information is based on the manufacturer's datasheet for the LM2853MH-2.5.
