摘要
Embodiments described herein relate to an LDO circuit device and overcurrent protection circuit of an LDO circuit. An overcurrent protection circuit is added to an LDO circuit to process an output current signal of the LDO circuit. When the output current signal of the LDO circuit increases, a voltage of a gate drive signal of a power switch in the LDO circuit is increased through adjustment performed by the overcurrent protection circuit, thereby declining the current capability of the power switch in the LDO circuit and restricting an output current thereof from continuing to increase. After feedback regulation, the output current of the LDO finally reaches to a stable value.
