LT3080EQ Description

Short technical summary and product information.

The LT3080EQ is a versatile 1.1A linear regulator designed for high current applications requiring adjustability to zero and no heat sink. It can be paralleled to increase output current or spread heat.

 

Key electrical specifications include a wide input voltage range of 1.2V to 36V and a low dropout voltage of 350mV. The output voltage is programmable using a single resistor, allowing for a range from 0V to 36V, with 1% initial accuracy of the SET pin current. It offers low output noise of 40µVRMS (10Hz to 100kHz) and excellent line and load regulation.

 

This regulator is stable with a minimum of 2.2µF ceramic output capacitance and includes internal protection circuitry for current limiting and thermal limiting. The LT3080EQ is available in various packages, including the DD-Pak, suitable for surface mount applications.

 

Applications include high current power supplies, post regulators for switching supplies, and variable voltage supplies where low parts count and low output voltage are critical.
