The LT1963AEQ-3.3#TRPBF is a 1.5A low dropout linear regulator from Linear Technology Corporation (LTC) designed for fast transient response and low output noise. It provides a stable 3.3V output voltage with a typical dropout voltage of 340mV at full load.
Key electrical characteristics include a quiescent current of 1mA, which drops to less than 1µA in shutdown mode. The regulator is optimized for sensitive RF applications due to its low output noise of 40µVRMS from 10Hz to 100kHz. It is stable with output capacitors as low as 10µF, including ceramic types.
This device is suitable for various applications such as 3.3V to 2.5V logic power supplies and post-regulation for switching supplies. Internal protection circuitry includes reverse battery protection, current limiting, and thermal limiting. The LT1963AEQ-3.3#TRPBF is supplied in an 8-lead SO package suitable for surface mounting.
The adjustable output voltage range is from 1.21V to 20V, offering design flexibility. The device requires an input voltage greater than 3V for proper operation.
