Embodiment Construction
[0037] The present invention will be further described below in conjunction with the drawings and specific embodiments.
[0038] The present invention provides a low-dropout linear regulator (hereinafter referred to as LDO) output dynamic adjustment circuit, such as Figure 4 As shown, a load control circuit 401, a dynamic output control circuit 402, an LDO output circuit 403, and a load circuit 404 are provided. Among them, the load control circuit 401 outputs a first control signal to dynamically adjust the load circuit 404 according to application requirements. The change of the load circuit 404 causes the required current to change; therefore, the load control circuit 401 also outputs the output signal according to the load change. Another second control signal controls the dynamic output control circuit 402; the dynamic output control circuit 402 then controls the LDO output circuit 403 to output the current required by the load circuit 404.
[0039] The load control circuit 4...
