Product Overview: LT1963EFE

The LT1963EFE is a high-performance, low dropout linear regulator from Linear Technology, designed to deliver fast transient response, low noise, and high power supply rejection ratio (PSRR) for sensitive applications. This regulator is well-suited for powering noise-sensitive circuits such as RF systems, analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and high-speed logic.

Key Features

• Output Voltage Range: The LT1963EFE offers an adjustable output voltage from 1.21V to 20V, which can be set by external resistors, providing great flexibility for various design requirements.
• High Current Output: It is capable of delivering up to 1.5A of continuous output current, making it suitable for high-power applications.
• Low Dropout Voltage: The low dropout voltage of typically 340mV at full load improves efficiency and allows operation close to the input supply voltage.
• Stable with Low ESR Capacitors: The device remains stable with ceramic, tantalum, or aluminum electrolytic capacitors, ensuring a wide range of output capacitance options.
• Low Noise: With a low noise of 40µVRMS over a 10Hz to 100kHz bandwidth, the LT1963EFE is ideal for sensitive applications where a clean power supply is crucial.
• High PSRR: High power supply rejection ratio of 65dB at 1kHz reduces the need for additional filtering and helps maintain a steady output despite variations in the input voltage.

Applications

The LT1963EFE is versatile and can be used in a variety of applications, including but not limited to:

• High-efficiency linear power supplies
• Post-regulation for switching supplies
