About this manual

The LM79XX series consists of 3-terminal negative voltage regulators available with fixed output voltages of -5V, -8V, -12V, and -15V. These devices are packaged in the TO-220 power package and are capable of supplying 1.5A of output current. They employ internal current limiting, safe area protection, and thermal shutdown to protect against virtually all overload conditions.
