Description and Introduction

1.5A/ Low Noise/ Fast Transient Response LDO Regulators The LT1963AEQ-3.3 is a low dropout (LDO) voltage regulator manufactured by Linear Technology (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Manufacturer:**  
- **LT (Linear Technology)**  

### **Specifications:**  
- **Output Voltage:** 3.3V (fixed)  
- **Output Current:** 1.5A  
- **Dropout Voltage:** 340mV (typical at full load)  
- **Input Voltage Range:** 2.7V to 20V  
- **Line Regulation:** 0.02% (typical)  
- **Load Regulation:** 0.05% (typical)  
- **Quiescent Current:** 1mA (typical)  
- **Shutdown Current:** <1µA  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 5-Lead DD-Pak (TO-263)  

### **Descriptions:**  
- The LT1963AEQ-3.3 is a high-performance LDO regulator designed for applications requiring low noise, high PSRR (Power Supply Rejection Ratio), and fast transient response.  
- It includes protection features such as current limiting, thermal shutdown, and reverse-battery protection.  
- Optimized for battery-powered and noise-sensitive applications.  

### **Features:**  
- **Low Dropout Voltage:** 340mV at full load  
- **High PSRR:** 75dB at 1kHz  
- **Low Noise:** 40µVRMS (10Hz to 100kHz)  
- **Adjustable Output (other variants):** The fixed 3.3V version does not require external resistors.  
- **Stable with Low-ESR Capacitors:** Works with ceramic capacitors (≥10µF).  
- **Thermal Shutdown & Current Limit Protection**  
- **Reverse Battery Protection**  

This regulator is commonly used in industrial, automotive, and portable electronics applications where stable and efficient voltage regulation is critical.
