Description and Introduction

3A Fast Ultra Low Dropout Linear Regulator The LP3853ES-1.8 is a low-dropout (LDO) voltage regulator manufactured by National Semiconductor (NS).  

### **Key Specifications:**  
- **Output Voltage:** 1.8V (fixed)  
- **Output Current:** Up to 1.5A  
- **Dropout Voltage:** Typically 340mV at full load (1.5A)  
- **Input Voltage Range:** 2.5V to 6.5V  
- **Accuracy:** ±1.5% over line, load, and temperature variations  
- **Quiescent Current:** 1.2mA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-263 (D2PAK-5)  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient regulation even with small input-output differentials.  
- **Fast Transient Response:** Suitable for dynamic load conditions.  
- **Thermal Shutdown & Current Limit Protection:** Prevents damage from overheating or excessive current.  
- **Stable with Low-ESR Capacitors:** Works with ceramic or tantalum output capacitors.  
- **Enable Pin (EN):** Allows for power management control.  

This regulator is designed for applications requiring high efficiency and reliability, such as power supplies for microprocessors, DSPs, and other low-voltage systems.
