The LT1963AEST-3.3PBF is part of the LT1963A series of low dropout linear regulators, designed for applications requiring fast transient response and low noise. This specific device offers a fixed output voltage of 3.3V and can supply up to 1.5A of output current.
Key electrical characteristics include a low dropout voltage of 340mV and very low output noise of 40µVRMS from 10Hz to 100kHz, making it suitable for sensitive RF applications. The quiescent current is 1mA during operation and drops to less than 1µA in shutdown mode. The regulator is stable with output capacitors as low as 10µF, including ceramic types.
Internal protection features include reverse battery protection, current limiting, and thermal limiting, enhancing reliability. The LT1963AEST-3.3PBF is available in a DD package, suitable for surface mount applications. Its design makes it ideal for 3.3V to 2.5V logic power supplies and as a post regulator for switching supplies.
