Additional Details

The LM140K-15/883QS provides a regulated +15V output with an output current capability of up to 1A. It incorporates internal thermal overload protection, which shuts down the regulator if the junction temperature exceeds a safe limit, preventing damage to the device. The short-circuit current limiting feature protects the regulator and the load from excessive current draw in the event of a short circuit. Additionally, the output transistor safe-area compensation ensures stable and reliable operation over a wide range of input voltages and output currents. The military-grade designation guarantees performance and reliability under extreme temperature and environmental conditions, making it suitable for use in critical applications where failure is not an option. It provides robust and stable power, ensuring optimal performance of connected circuitry.
