Negative voltage regulation circuit and voltage generation circuit including the same

摘要

A negative voltage regulation circuit includes an operational amplifier configured to receive a feedback voltage and an input voltage, a pull-up element configured to pull-up drive a first node based on output voltage of the operational amplifier, a load element coupled between the first node and a negative voltage terminal, a pull-down element configured to pull-down drive a final negative voltage output terminal using a voltage of the negative voltage terminal based on a voltage level of the first node, and a voltage division unit coupled between the final negative voltage output terminal and a pull-up voltage terminal, and configured to generate the feedback voltage by voltage division.
