Standard Application Circuit
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.
