LT3083IT Description

Short technical summary and product information.

The LT3083IT from Analog Devices is a versatile 3A low dropout linear regulator. Architected as a precision current source and voltage follower, it is designed for applications requiring high current and adjustability to zero volts without a heatsink. The device features a low dropout voltage of 310mV and can be paralleled to increase output current or spread heat.

Key electrical specifications include an output current of 3A, a set pin current of 50µA with 1% initial accuracy, and an output adjustable to 0V. It operates over a wide input voltage range of 1.2V to 23V and provides low output noise of 40µVRMS (10Hz to 100kHz). Load regulation is less than 1mV, and line regulation is less than 0.001%/V. The LT3083IT is stable with a minimum of 10µF ceramic capacitor on the output.

Available in multiple package options including DD-PAK, TO-220, TSSOP, and DFN, the LT3083IT is suitable for various mounting types, including surface mount and through-hole. Internal protection circuitry includes current limiting with foldback and overtemperature protection, making it a robust choice for power management applications.
