[0028] As mentioned in the background art, the power consumption of the voltage regulator in the prior art is still very high and needs to be further reduced to meet the needs of wearable electronic devices.
[0029] The inventor of the present application analyzed the prior art voltage regulator. figure 1 It is a schematic structural block diagram of a voltage regulator in the prior art. Such as figure 1 As shown, the patent document US7579822 discloses a low-power high-precision bandgap voltage reference circuit. The reference circuit may include a high-power bandgap reference circuit 66 and a low-power bandgap reference circuit 68, which respectively generate reference voltages. V BG_H And V BG_L , To supply power to the powered device 150, where the powered device 150 includes a high power consumption circuit 152 and a low power consumption circuit 154. The reference circuit can work in a first mode and a second mode. When the reference circuit works in the first mode, th...
