LM140K-15 General Description

The LM140K-15 is a voltage regulator integrated circuit (IC) manufactured by Texas Instruments. It is part of the LM140 series, known for its high-performance voltage regulation capabilities. The "15" in its name indicates that the output voltage is fixed at 15 volts. This regulator operates as a fixed linear regulator, meaning it maintains a constant output voltage regardless of variations in input voltage or load conditions.The "K" in its name signifies the package type, which in this case is a TO-3 metal can package. This package provides robustness and efficient heat dissipation, suitable for various industrial and commercial applications.The LM140K-15 offers a maximum output current of up to 1.5 amperes, making it suitable for powering medium to moderately high current loads. It features low dropout voltage and excellent line and load regulation characteristics, ensuring stable voltage output across a wide range of operating conditions.
