Description and Introduction

1.5A, Low Noise, Fast Transient Response LDO Regulators The LT1963EQ#PBF 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 Range:** Adjustable from 1.21V to 20V or fixed voltages (1.5V, 1.8V, 2.5V, 3.3V, 5V).
- **Output Current:** 1.5A.
- **Dropout Voltage:** 340mV typical at full load.
- **Input Voltage Range:** 1.8V to 20V.
- **Line Regulation:** 0.02% typical.
- **Load Regulation:** 0.05% typical.
- **Quiescent Current:** 1mA typical (operating), <1µA (shutdown).
- **Operating Temperature Range:** -40°C to +125°C.
- **Package:** 5-Lead DD-Pak (TO-263).

### **Descriptions:**
- The LT1963EQ#PBF is a high-performance LDO regulator designed for applications requiring low noise, high PSRR, and fast transient response.
- It features low dropout voltage, making it suitable for battery-powered and high-efficiency systems.
- The device includes protection features such as current limiting, thermal shutdown, and reverse-battery protection.

### **Features:**
- **Low Noise:** 40µVRMS output noise (10Hz to 100kHz).
- **High PSRR:** 75dB at 1kHz.
- **Fast Transient Response:** Optimized for stability with low-ESR capacitors.
- **Adjustable & Fixed Output Options:** Versatile for various applications.
- **Protection Features:**  
  - Overcurrent protection.  
  - Thermal shutdown.  
  - Reverse-battery protection.  
  - No reverse current flow.
- **Wide Input Voltage Range:** Supports operation down to 1.8V.
- **Low Quiescent Current:** Enhances efficiency in battery-operated systems.

This regulator is commonly used in industrial, automotive, and portable electronics where stable, low-noise power is critical.
