A power element bypass and voltage regulation circuit shutdown is used in a low drop out (LDO) bypass voltage regulator to minimize current drawn by the voltage regulator circuit when the supply input voltage approaches the regulated output voltage of the voltage regulation circuit. Two modes of operation are used in the low drop out (LDO) bypass voltage regulator. A regulate mode is used when the supply input voltage is greater than the reference voltage input, and a track mode is used when the supply input voltage is less than or equal to approximately the regulated output voltage of the voltage regulation circuit. Hysteresis may be introduced when switching between the regulate and track modes of operation.
