Abstract
This invention relates to a voltage regulated circuit, more particularly, to a voltage regulated circuit with a well resistor divider. The present invention applies two well resistors act as the voltage regulated circuit and uses the characteristic of the well resistor in the resistance value, which is increased following the voltage that is transmitted to the well resistor to make an output voltage become a stable value. When the input voltage is an instable and over-high value, the depletion region in the well resistor will extend to absorb the over-high voltage value and make the output voltage to become a stable voltage value.
