LM2990T Description

Short technical summary and product information.

The LM2990T-12 from Texas Instruments is a 1-A, negative low-dropout (LDO) voltage regulator. This three-terminal device offers a fixed output voltage of -12V, making it suitable for various power management applications.

Key electrical specifications include an input voltage range of -26V to -6V and a typical dropout voltage of 0.6V at a 1A load. The regulator maintains an output accuracy of 5% over the entire operating range. It also features a low quiescent current of 1mA and provides internal short-circuit current limiting and thermal shutdown with hysteresis for protection.

The LM2990T-12 is available in a TO-220 package, designed for through-hole mounting. Its operating temperature range is -40°C to 125°C. This regulator is functionally complementary to the LM2940 series and is often used in post-switcher regulation, local on-card regulation, and battery-operated equipment.

This component is classified as a Single Channel LDO within the Linear Regulator category.
