LM79M12CT Description

Short technical summary and product information.

The Texas Instruments LM79M12CT is a 3-terminal negative voltage regulator designed for applications requiring a fixed -12V output. It can supply up to 500mA of output current and features internal current limiting, safe area protection, and thermal shutdown for protection against overload conditions.

 

This regulator requires only one external component, a compensation capacitor at the output, for stability. It offers high ripple rejection and a 4% tolerance on the preset output voltage. The device is packaged in a TO-220 power package, suitable for through-hole mounting.

 

Key electrical characteristics include a typical voltage dropout of 1.1V at 500mA and a PSRR of 70dB at 120Hz. The operating temperature range is from 0°C to 125°C. These features make the LM79M12CT suitable for various power supply applications where a stable negative voltage is required.
