Line regulation and transient line regulation
The line regulation (LiR) is a static variable that indicates the change in the output voltage of
the voltage controller ΔV
voltage.
By contrast the line transient response (LiTr) represents dynamic peak value to be observed
during the change in input voltage
Thermal effects due to changes in the junction temperature are circumvented with pulsed
voltage during the test and are to be taken into account separately.
The figure shows the boundary conditions for t
the measurement of the line transient response without additional decoupling of the supply
voltage by a buffer capacity C
