A method to adjust the load transient regulation of a low drop-out (LDO)/load switch linear voltage regulator (LVR) with an n-type pass element having an open loop transfer function, including determining during a load transient event if the gate of the pass&#x2014;element goes lower than a scaled value of the output voltage or a constant voltage level, generating a control signal that controls a current sink block if the gate voltage of the pass element is lower than the output voltage, and enabling a current sink block that is controlled by the control signal and connecting the output of the current sink block to the output of the LVR.

Circuit to improve load transient behavior of voltage regulators and load switches

A low drop-out (LDO)/load switch linear voltage regulator (LVR) circuit having a first input terminal and a first output terminal, includes: a passive network with a second input terminal connected to the first input terminal and a second output terminal; a feedback network with a third input terminal connected to the first output terminal and a third output terminal; a pass element having a fourth input terminal connected to the first input terminal, a fourth output terminal connected to the first output terminal and first control terminal; a combiner having a fifth input connected to the second input, a sixth input connected to the third output and a fifth output connected to the first control terminal.
