REGULATOR WITH IMPROVED WAKE-UP TIME |
摘要 |
A regulating circuit includes a first comparator configured to control a turning on and a turning off of a first transistor based on a first comparison a reference voltage to a feedback voltage. The first transistor is coupled between an output node and a first voltage supply. A second comparator is configured to control a turning on and a turning off of a second transistor based on a second comparison of the reference voltage to the feedback voltage. The second transistor is coupled to the output node. A high-impedance circuit is coupled in series with the second transistor such that the high-impedance block is disposed between the second transistor and a second power supply. The high-impedance circuit is configured to generate a constant current between the output node and the second voltage supply when the second transistor is turned on. |
