The LT1963AEST-3.3#PBF is a low dropout (LDO) linear voltage regulator designed for applications requiring fast transient response and low noise. It provides a stable 3.3V output voltage and can supply up to 1.5A of current. The device operates with a low quiescent current of 1mA, which drops to less than 1µA in shutdown mode.
Key electrical characteristics include a typical dropout voltage of 340mV at 1.5A and low output noise of 40µVRMS from 10Hz to 100kHz. The regulator is stable with output capacitors as low as 10µF, including ceramic types. Internal protection circuitry includes reverse battery protection, current limiting, and thermal limiting.
This regulator is available in a surface mount SOT-223-3 package, suitable for compact designs. Its operating temperature range is -40°C to 125°C. The LT1963AEST-3.3#PBF is ideal for sensitive RF power supplies, post-regulation for switching supplies, and 3.3V to 2.5V logic power supplies.
