Standard Application Circuit
LM79XX
A common ground is required between the input and the output voltages. The input voltage must remain typically 2.0V above the output voltage even during the low point on the Input ripple voltage. XX = these two digits of the type number indicate voltage. * = Cin is required if
regulator is located an appreciable distance from power supply filter. ** = Co is not needed for stability; however, it does improve transient response.
