The LT1963AEQ-1.8#TRPBF is a high-performance, low dropout linear regulator from Linear Technology that delivers a continuous output current of up to 1.5A with a dropout voltage of typically 340mV at full load. This regulator is designed for applications requiring low noise, fast transient response, and high power supply rejection ratio (PSRR).

Key Features

• Output Voltage: Fixed at 1.8V, providing a stable and precise voltage for critical applications.
• High Output Current: Capable of delivering 1.5A of continuous output current, making it suitable for powering a variety of loads.
• Low Dropout Voltage: A low dropout voltage of 340mV ensures efficient operation even when the input-to-output voltage differential is minimal.
• Excellent Noise Performance: With an output noise as low as 40μV RMS, this regulator is ideal for sensitive RF and analog circuitry.
• Fast Transient Response: The device's quick response to load changes makes it ideal for applications with varying load conditions.
• Stable with Low ESR Capacitors: The LT1963AEQ-1.8#TRPBF remains stable with ceramic, tantalum, or aluminum electrolytic capacitors, offering flexibility in design.
• Thermal Protection: Built-in thermal shutdown and current limit protections safeguard the device and the application from over-current and over-temperature conditions.
