The present invention discloses a power-on reset circuit based on LDO, which belongs to the field of integrated circuits, including an operational amplifier AMP, a logic module, resistors R1-R6, switches SW1-SW2, PMOS tubes M0-M2, PMOS tube M4, NMOS tube M3, and a comparator CMP; in the present invention, the addition of NMOS tube M3 not only overcomes the shortcomings of the traditional capacitive POR circuit that the power-on speed is slow and the reset signal cannot be correctly generated when the power is quickly lost, but also avoids the phenomenon of erroneous triggering when the voltage is too low. The use of two-way switches provides a hysteresis voltage in the voltage rising and falling sections, so that the circuit will not generate an erroneous reset signal when it is disturbed, greatly improving the stability of the circuit. The use of LDO avoids the use of triodes in the bandgap POR circuit and reduces the circuit area. The overall structure uses a simple LDO, two switches and a comparator to generate a reliable reset signal, and the circuit structure is simple and practical.
