Multimode voltage regulator and method for providing a multimode voltage regulator output voltage and an output current to a load |
摘要 |
A multimode voltage regulator comprises an output for providing a regulator output voltage Vdd and an output current to a load and a low power reference voltage source having a reference voltage output providing the regulator output voltage Vdd, when in a first low power mode the output current is not greater than a threshold value. It may comprise a buffer amplifier having an output providing the regulator output voltage Vdd, when the output current is greater than the threshold value and a first bias voltage input being connected in a second low power mode to the reference voltage output when the output current is greater than the threshold value for less than a predefined time. And it may comprise a mode controller for automatically determining the output current and automatically switching from first low power mode to second low power mode. |
