means that the test should be carried out with the test time so short (within 10mS), that the drift in
characteristic value due to the rise in chip junction temperature can be ignored.

A common ground is required between the input and the output voltages. The input voltage must remain typically 2.0 V
more negative even during the high 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 improves stability and transient response.
