LM1085IT-3.3 Description

Short technical summary and product information.

The LM1085IT-3.3 from Texas Instruments is a 3-Ampere low-dropout (LDO) positive linear voltage regulator. It is designed to provide a stable output voltage with a maximum dropout voltage of 1.5V at 3A load current. This regulator features current limiting and thermal shutdown protection for enhanced reliability.

 

Key electrical specifications include an input voltage range of 2.6V to 29V and a fixed output voltage of 3.3V. It offers a typical output current of 3A, with line regulation at 0.015% and load regulation at 0.1%. The device also provides a PSRR of 30dB at 100 KHz and a typical quiescent current of 5mA.

 

This component is available in a TO-220-3 package, suitable for through-hole mounting. The operating temperature range is -40°C to 125°C (TJ), making it suitable for various industrial applications. The LM1085 series is known for its similar pin-out to the industry-standard LM317.
