Abstrakt
A system and method for controlling a low-dropout regulator (LDO) is disclosed. The system and method includes a charge pump that is controlled to provide a charge pump voltage to power the LDO. The charge pump voltage can be adjusted relative to the LDO's input voltage to ensure efficient operation of the LDO for input voltages over a range. The charge pump is also controlled to limit the maximum charge pump voltage provided to ensure safe operation of the LDO. The system and method also includes a under voltage lockout circuit that enables the LDO when it is determined that the charge pump voltage is sufficient to meet multiple criteria enable For example, the charge pump voltage may be analyzed to determine if it is above a minimum voltage and also sufficiently higher than the LDO's output voltage.
