General Description

The LM78G and LM79G are 4-terminal adjustable voltage regulators. They are designed to deliver continuous load currents of up to 1.0A with a maximum input voltage of + 40V for the positive regulator LM78G and -40V for the negative regulator LM79G. Output current capability can be increased to greater than 1.0A through use of one or more external transistors. The output voltage range of the LM78G positive voltage regulator is +5V to +30V and the output voltage range of the negative LM79G is -30V to -2.55V. For systems requiring both a positive and negative, the LM78G and LM79G are excellent for use as a dual tracking regulator with appropriate external circuitry.
