Description and Introduction

1.5A/ Low Noise/ Fast Transient Response LDO Regulators The LT1963AEQ-1.8 is a low dropout (LDO) linear regulator manufactured by Analog Devices (formerly Linear Technology). Below are the factual specifications, descriptions, and features from the manufacturer's datasheet:

### **Manufacturer:**  
Analog Devices (formerly Linear Technology)  

### **Part Number:**  
LT1963AEQ-1.8  

### **Description:**  
The LT1963AEQ-1.8 is a fixed-output, low dropout voltage regulator with an output voltage of **1.8V**. It is designed to deliver up to **1.5A** of output current with a low dropout voltage of **340mV** (typical at full load).  

### **Key Features:**  
- **Output Voltage:** Fixed **1.8V**  
- **Output Current:** Up to **1.5A**  
- **Low Dropout Voltage:** **340mV** (typical at full load)  
- **Low Noise:** **40µV RMS** (10Hz to 100kHz)  
- **Wide Input Voltage Range:** **1.8V to 20V**  
- **Adjustable Output (Other Variants):** The LT1963 series includes adjustable versions, but the LT1963AEQ-1.8 is fixed at 1.8V.  
- **Fast Transient Response:** Optimized for stability with low ESR capacitors (≥10µF)  
- **Protection Features:**  
  - **Reverse Battery Protection**  
  - **Reverse Current Protection**  
  - **Thermal Shutdown**  
  - **Current Limit with Foldback**  
- **Operating Temperature Range:** **-40°C to +125°C**  
- **Package:** **5-Lead DD-Pak (TO-263)**  

### **Applications:**  
- Battery-powered systems  
- High-performance digital circuits (FPGA, DSP, ASIC)  
- Post-regulation for switching supplies  
- Noise-sensitive applications  

This information is sourced from the official LT1963 datasheet by Analog Devices (Linear Technology). For detailed electrical characteristics and application circuits, refer to the datasheet.

Description and Introduction

1.5A/ Low Noise/ Fast Transient Response LDO Regulators The LT1963AEQ-1.8 is a low dropout (LDO) voltage regulator manufactured by **Linear Technology (now part of Analog Devices)**. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Output Voltage:** 1.8V (fixed)  
- **Output Current:** 1.5A  
- **Dropout Voltage:** 340mV (typical at full load)  
- **Input Voltage Range:** 2.3V to 20V  
- **Line Regulation:** 0.02% (typical)  
- **Load Regulation:** 0.05% (typical)  
- **Quiescent Current:** 1mA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 5-Lead DD-Pak (TO-263)  

### **Descriptions:**  
- Designed for high-performance applications requiring a stable, low-noise power supply.  
- Features fast transient response and low output noise.  
- Includes built-in protection against reverse battery, reverse current, and thermal overload.  

### **Features:**  
- **Low Dropout Voltage:** 340mV at full load.  
- **Low Noise:** 40μVRMS (10Hz to 100kHz).  
- **Adjustable Output (Other Variants):** While this model is fixed at 1.8V, other LT1963 variants support adjustable output.  
- **Stable with Low-ESR Capacitors:** Works with ceramic capacitors (≥10μF).  
- **Protection Features:**  
  - Reverse battery protection.  
  - Reverse current protection.  
  - Thermal shutdown.  

This regulator is commonly used in **battery-powered systems, industrial equipment, and RF/mixed-signal circuits** where precise voltage regulation is critical.  

(Note: Always refer to the official datasheet for detailed specifications and application guidelines.)
