The LM140LAH-12 from Texas Instruments is a three-terminal positive linear voltage regulator with a fixed 12V output. Designed for a wide range of applications, it can supply up to 100mA of output current.
Key electrical specifications include a line regulation of 0.04%/V and a load regulation of 0.01%/mA. The device features internal thermal overload protection and short circuit current limiting for enhanced reliability. It operates over an extended temperature range of -55°C to 125°C.
Packaged in a TO-39-3 metal can (TO-205AD), this regulator is suitable for through-hole mounting. Its design allows for local on-card regulation, simplifying power distribution and improving system stability. The LM140LAH-12 is an improved version of the LM78LXX series, offering tighter output voltage tolerance and better regulation.
This regulator is useful in logic systems, instrumentation, and other solid-state electronic equipment where a stable, fixed positive voltage is required.
