The LM2990T-12 from Texas Instruments is a three-terminal, low-dropout, negative voltage regulator. It provides a fixed output voltage of -12V and can supply an output current in excess of 1A, with the product data listing up to 1.8A. The device features a low quiescent current, typically 1 mA under normal load conditions, and an internal short-circuit current limit and thermal shutdown for enhanced reliability.
Designed for applications requiring stable negative voltage rails, the LM2990T-12 operates over a wide input voltage range of -26V to -6V. Its dropout voltage is typically 0.6V at a 1A load, with a maximum of 1V across the entire operating temperature range of -40°C to 125°C. The output accuracy is maintained at 5% over load and temperature extremes.
This regulator is available in a TO-220-3 package, suitable for through-hole mounting. Its features make it ideal for post-switcher regulation, local on-card regulation, and battery-operated equipment where efficient power management is crucial.
