Standard Application Circuit
79M05/79M12
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.
