Abstract

Systems and methods for pin lift detection compensation in Low Dropout (LDO) regulators. In an illustrative, non-limiting embodiment, a System-On-Chip (SoC) may include: a circuit; and an LDO regulator coupled to the circuit, where the LDO includes a transistor having a first terminal coupled to a first voltage rail and a second terminal coupled to the circuit, where the second terminal is configured to receive a probe current produced from a second voltage rail, and where the first voltage rail is coupled to a compensating current source configured to draw a compensating charge equal to or greater than a charge imparted upon the second terminal by the probe current.
