LM140K-5.0 Description

Short technical summary and product information.

The Texas Instruments LM140K-5.0 is a monolithic 3-terminal positive voltage regulator capable of delivering over 1.0A output current with adequate heat sinking. This device features internal current-limiting, thermal shutdown, and safe-area compensation, making it highly robust.

 

With a fixed 5V output voltage and a maximum output current of 1A, the LM140K-5.0 is suitable for various local on-card regulation applications. It operates within an input voltage range of 17.6V to 35V and features a typical dropout voltage of 2500mV at 1A. The regulator is housed in a TO-3 package and designed for through-hole mounting.

 

Key electrical characteristics include a quiescent current of 7mA typical, noise of 40µVrms, and PSRR of 50dB at 100 KHz. The output voltage tolerance is ±4% at 25°C. The operating temperature range is -55°C to 125°C, and it includes internal protection against over-temperature and short circuits.

 

This regulator is ideal for applications requiring a stable, fixed positive voltage supply. Its inherent protection features and robust design contribute to its reliability in demanding environments.
