The LT1963AEST-3.3#PBF is a low dropout linear regulator from Analog Devices, designed for applications requiring fast transient response and low noise. It can supply up to 1.5A of output current with a typical dropout voltage of 340mV.
Key electrical characteristics include a low quiescent current of 1mA, which drops to less than 1µA in shutdown mode. The regulator is stable with output capacitors as low as 10µF and is suitable for sensitive RF supply applications due to its low output noise of 40µVRMS (10Hz to 100kHz).
This device offers an adjustable output voltage range from 1.21V to 20V, with fixed output voltages also available. Internal protection circuitry includes reverse battery protection, current limiting, and thermal limiting. The LT1963AEST-3.3#PBF is supplied in an 8-lead SO package suitable for surface mounting.
Applications include 3.3V to 2.5V logic power supplies and post-regulation for switching supplies. The device requires an input voltage greater than 3V for operation.
