LM340T-12 Description

Short technical summary and product information.

The Texas Instruments LM340T-12 is a monolithic 3-terminal positive voltage regulator designed for various applications requiring a stable 12V output. It can deliver up to 1.5A of output current, provided adequate heat sinking is supplied. The device features internal current-limiting, thermal shutdown, and safe-area compensation, making it robust against overloads and short circuits.

 

Key electrical specifications include an input voltage range of 7.5V to 35V, a typical dropout voltage of 2V at 1A, and a typical quiescent current of 6.5mA. The regulator offers a typical PSRR of 50dB at 100 KHz and an accuracy of 2.5%. It is available in fixed output voltage options of 5V, 12V, and 15V.

 

The LM340T-12 is supplied in a TO-220-3 package, suitable for through-hole mounting. The operating temperature range is from 0°C to 125°C. Its internal protection features contribute to its reliability in demanding applications.
