摘要： The invention provides a load monitor,. The load monitor is configured to monitor a load status of a core, and control, according to the load status of the core, a low dropout regulator LDO to output a voltage to the core. The load monitor includes a control module and a monitoring module. A monitoring end of the monitoring module is connected to a signal output end of the core. An output end of the monitoring module is connected to an input end of the control module. A control end of the control module is connected to an input end of the monitoring module. An output end of the control module is connected to a control end of the LDO. An output end of the LDO is connected to a voltage input end of the core. The control module is configured to control the monitoring module to operate or power off.

摘要： This application relates to the field of integrated circuits, and provides a voltage regulation circuit and a voltage regulation method. The voltage regulation circuit includes at least one switch module (1), at least one obtaining module (2), at least one control module (3), and at least one load (4), and the at least one switch module (1), the at least one obtaining module (2), the at least one control module (3), and the at least one load (4) are in a one-to-one correspondence. Each of the at least one obtaining module (2) may obtain load information of a corresponding load (4), and output the load information to a corresponding control module (3), and the corresponding control module (3) may generate a switch control signal based on the load information. Because the switch control signal generated by the corresponding control module (3) is an accurate signal, after the switch control signal is output to a corresponding switch module (1), the corresponding switch module (1) may regulate, based on the accurate switch control signal, a voltage input to the corresponding load (4), so as to improve voltage regulation accuracy and reliability.
