CIRCUIT TO IMPROVE LOAD TRANSIENT BEHAVIOR OF VOLTAGE REGULATORS AND LOAD SWITCHES
摘要:
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—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.
