Abstract
Based on the power-up/power-down control, the paper describes a low quiescent current and reset time adjustable power-on reset (POR) circuit, which is integrated in a regulator. Compared with the conventional RC reset circuit, it can provide more accurate reset pulse at slow power up and twinkling power down. And when the chip works properly, parts of the power-on reset circuit are shut down, then the quiescent current of the POR is reduced by 12muA. In addition, the power-on reset time can be adjusted based on different applications
