Abstract
A significant reduction of the amplitude of the transient response is obtained by keeping a low dropout regulator circuit in a closed loop condition. This is achieved by manipulation of the reference voltage level when an open loop condition arises due to a falling input voltage. In this case, the reference voltage level is tracked with the input voltage level, keeping the output voltage regulated. As a consequence, the power pass element of the regulator is not forced into the linear region (in the case of a MOSFET) or deep saturation (in the case of a bipolar transistor).
