MUMBAI, India, Nov. 21 -- Intellectual Property India has published a patent application (202517098130 A) filed by Vanchip (TIANJIN) Technology Co. Ltd., Tianjin, China, on Oct. 11, for 'low dropout regulator with over-current protection, and chip and electronic device.'
Inventor(s) include Wang, Yongshou; Liang, Shengyu; and Chen, Cheng.
The application for the patent was published on Nov. 21, under issue no. 47/2025.
According to the abstract released by the Intellectual Property India: "A low dropout regulator (LDO) with over-current protection, and a chip and an electronic device. The LDO comprises an LDO main circuit (100), a high-precision current sampling circuit (200), and an over-current protection control loop (300), wherein an output end of the LDO main circuit (100) is connected to an input end of the high-precision current sampling circuit (200), an output end of the high-precision current sampling circuit (200) is connected to an input end of the over-current protection control loop (300), and an output end of the over-current protection control loop (300) is connected to both the LDO main circuit (100) and the high-precision current sampling circuit (200), so as to form a closed control loop. When the current of a load exceeds a current-limiting value, the LDO can effectively protect a power tube (MP0) of the LDO main circuit (100) and the load, and a hard shutoff phenomenon of a system may not occur."
The patent application was internationally filed on Mar. 12, 2024, under International application No.PCT/CN2024/081279.
